Early years

The club was founded in 1934 with the enthusiastic support of the town's Cedars Grammar School with which it has always maintained a close support. The club flourished during those early years, playing its home matches at the Cricket Club's Bell Close headquarters, but like many others, was disbanded with the outbreak of World War II. Many of the founder members did not return from the hostilities and probably in consequence the club was not reformed until mid-way through season 1948–49. Several successful seasons followed, with the club supported by local schools and locally based service personnel, but fell into decline and was disbanded at the end of the 1955–56 season. Rugby during this immediate post-war period was played at the Capshill Meadow on the Hockliffe Road which is just big enough for one pitch.

The club of today arguably owes its existence to the enthusiasm of a 19-year-old Howard Ansdell who initiated the reforming of the club in time for the 1958–59 season and to local businessman Geoff Wright who steered the club into erecting its first clubhouse in 1962, and in 1965 to the purchase of the Capshill Meadow ground. Proceeds from the sale of the ground in 1973 established the splendid facilities we now enjoy. The move to Stanbridge Road occurred at a time when the Town was expanding and with many new players available to the club, was able to attract much stronger fixtures for its Senior XV. The transformation of Cedars Grammar to a comprehensive did not stop the flow of good rugby players to the club as rugby remained the primary winter sport at the school. Thanks to Cedars, Leighton was always able to punch above its weight for a club from a relatively small town. Each of the club's six sides would always have a good representation of Old Cedarians.

The slow build (1960s and 1970s)

Admirably fed by a regular intake of players from particularly the Cedars but also the Vandyke Schools, Buzzards grew in stature so that by the 1970s they had a strong fixture list and almost always finished a season with more wins than losses. During this time the club built a strong bond with the club from Leighton Buzzard's French twin town Coulommiers in the Seine-et-Marne department in the Ile de France region. On one memorable occasion the club also stepped in to host top Romanian club CSA Steaua București when bad weather had forced the cancellation of one of their tour matches. At that time Romanian rugby was a force to be reckoned with and if not close to acceptance into the then Five Nations Championship, then they ought to have been as they would score reasonably regular victories over France, Wales and Scotland.

Years of success (1980–1995)

The club's golden period could be traced from the early- to mid-80s through to the mid-90s. Prior to the RFU's implementation of a national league structure, the only measure of success for junior clubs like Leighton were the cup competitions of the RFU constituent county bodies. Winning the County Cup enabled a club to gain entry to the following season's National Knockout Cup and the chance to have a tilt at one of the big clubs. In Leighton Buzzard's case this came in the shape of the East Midlands Cup for clubs based in Bedfordshire and Northants. In 1985–86, Paul Whiting became the first Buzzards skipper to lift the Cup when Peterborough were beaten 16-6 in the final. The draw for the following season's National Cup, then called the John Player Cup, saw them paired with Birmingham, at the time a club on the cusp of first class status who were later to become Birmingham & Solihull R.F.C. Led by David Yirrell, Buzzards produced the upset of the round winning 20–11. Buzzards fell at the next hurdle to Lichfield but with confidence brimming the season culminated with the retention of the East Midlands Cup when Northampton Trinity were beaten 18-8 at Franklin's Gardens.

The following season, the inaugural season of league rugby in England, saw Buzzards placed in Midlands Division 2 (East). They also made their second appearance in the John Player Cup as a result of their County Cup win. Again they conquered higher ranked opposition in the first round when Derby, then of National Division 4 (North), were beaten 10–7 in a close encounter at Leighton Road (the name 'Wright's Meadow' was still to be coined). The second round draw paired them with first class opposition in the form of nearby Bedford Blues, again at home. Led by John Orwin who was to captain England later that season, and also including former and future Buzzard stalwarts in Pete Ellam and John Davidson, Bedford had to work hard to subdue a spirited Buzzards effort. Buzzards conceded just one try in a 24–6 defeat in front of probably the largest crowd to assemble at the ground. Later that season their attempt to land a hat-trick of East Midlands Cup wins was dashed at the last when they fell to Stockwood Park in the final. A fifth place in their first league campaign was a disappointing return for a season that had started with such promise. However this disappointment was tempered slightly by the RFU's decision to expand the entry to the following season's National Cup, now to be called the Pilkington Cup, meaning that Leighton would be included as East Midlands Cup Runners-Up.

In 1988–89 with John Fraser now installed as skipper, the second season of league rugby was a successful one as they finished as champions of Midlands 2 (East) to bring about what became a five-season stay in Midlands Division 1 (now named Regional 1 Midlands). At the time this was the fifth tier of the National League structure. Their National Cup heroics didn't quite reach their previous heights as they made an 18–12 first round exit to Hereford.

In 1993–94 the club suffered their first relegation dropping back into what was now Midlands Division 2 (the East/West split having been discarded for 1994–95). In terms of silverware the Club now embarked on probably its most successful season. Under the captaincy of Ian Smith, the league title was secured with a win in the last-day winner-takes-all clash against Broadstreet at Wright's Meadow that ensured an immediate return to Midlands Division 1. Not only was there the league success but the Bedfordshire Cup was regained and the East Midlands Cup won for a third (and to date last) time with local rivals Stockwood Park vanquished in both finals.

60th anniversary and beyond

There followed the club's 60th anniversary season which began with celebration matches against Aylesbury, who had been the club's first opponents in 1934, and a side representing top division club Wasps. The East Midlands Cup win of the previous April had also given them another Pilkington Cup excursion. Again they were paired with Birmingham & Solihull. Though this time they had home advantage, history was not to be repeated and their campaign faltered at the first hurdle as they went down 29–11. By now, with the league system having taken deep root very quickly, a club's position within the league structure was now seen as all important with the Pilkington Cup now seen as a diversion, albeit a pleasant one with some kudos if early rounds could be successfully negotiated. Buzzards achieved their primary aim in their first season back in Midlands 1 by consolidating its place with a 10th-place finish in the 13-team table.

The club's most successful league campaign came in the 1997–98 when Carl Siddon led them to a mid-table finish in Midlands Division 1. The following season, however, saw a sharp decline in playing strength and performance and inevitably relegation followed. The club has not been at Level 5 since.

During 2022-2023 the club is fielding two adult senior sides plus a Colts and Ladies XVs. In recent times the club also fielded three additional senior sides, a Veterans (over 35's) XV. The club relies heavily on developing players from within its own ranks and is very proud of its long-established Mini/Junior section which currently boasts a membership of approximately 200 children aged between 5 and 17 years. Never having had a large benefactor may have meant that Buzzard's senior league position has slipped, but it has meant that the club still belongs to the town and the members and retains the "club feel". The 1st XV starting line up and subs for the side's last home League match of the successful 2013–14 season contained 11 players whose fathers had also played for the club.

Signs that their star might be in the ascendant once more came in 2006–07 when the Colts XV swept the board winning the East Midlands League and Cup competitions along with the Bedfordshire Cup. The side was captained by Ryan Fraser emulating his father John in lifting silverware in the name of LBRFC. A majority of those Colts players filtered into the senior setup and kept the club at a good standard.

In March 2020 the club won the Midlands Final of the RFU Intermediate Cup beating Malvern 30-16 at Wright's Meadow despite being reduced to 14 men early in the match. The draw for the national semi-finals saw them handed a home tie against Halifax-based Old Brodleians who had won the Northern Division final. Sadly the match was never played owing to the COVID-19 pandemic which saw the eventual cancellation of the competition. Thus Buzzards, Brodleians and the South West and London Division semi-finalists Wellington and Old Colfeians were left stranded, one step away from a Twickenham final.

Still, from those humble beginnings in 1934 LBRFC now provides a sporting centre with which the town has every right to be proud. However, as an organisation, fully aware that standing still is not an option, the club's committee are actively looking at ways of improving the facilities for the playing of sport and enjoyment of associated social activities.
