Wake Up, Jeff!

Fatt's schtick was sleeping at odd times, which led to a Wiggles catchphrase and the title of one of their songs, "Wake Up, Jeff!" Fatt was the oldest Wiggle and was well known for his "laid-back personality",^[3] which according to Field, made him "invaluable company on the road".^[10] As Sam Moran has said, when referring to the development of the Wiggles' shticks, "Jeff really does fall asleep",^[11] and Fatt reported, "The irony is I'm a very light sleeper in the nighttime. I will invariably have a snooze before the show".^[12] Fatt was the only member of the Wiggles without a background in early childhood education; he stated that was the reason falling asleep was chosen as his schtick, "because it was a way of getting me involved in the shows without actually having to do anything".^[13] Field claimed Fatt's schtick endeared Fatt to their audiences and called it "a simple audience participation and interaction gag we've done since the start of the group".^[5]

Kathleen Warren, the group's former professor at Macquarie University and their consultant for their shows and DVDs, believed that the shtick empowered children,^[14] and Paul Field reported that children in the Wiggles' audience felt "great excitement" and were disappointed if not given the opportunity to help Jeff in this way.^[15]

Anthony Field reported that although in the early days of the group, they took turns falling asleep, it became Fatt's schtick because "it was a perfect fit".^[5]

Retirement

"Wiggly concert": Balloon versions of Jeff and Murray

On 17 May 2012, it was announced that Fatt along with Greg Page and Murray Cook, would be retiring at the end of the year. Wiggles cast member Lachlan Gillespie replaced him as the purple Wiggle. Fatt and the others are expected to remain involved with the creative and production aspects of the group. He continues to perform in reunion shows.^[16]

In July 2020, he appeared with the other classic Wiggles in The Soul Movers music video "Circles Baby".^[17] In September 2020, following the announcement of the birth of Gillespie's daughters, Lulu and Lottie,^[18] it was announced Gillespie would take some time away from the group in order to spend time with them. As a result, Fatt decided to temporarily replace Gillespie to film The Wiggly World Of Dance Classes, a four-part series. Fatt has made appearances in the newest Wiggles series, season 3 of Ready, Steady, Wiggle and has returned as the voice of Henry the Octopus.^[19]

Family

Fatt was featured on the fourth episode of the twelfth season of Who Do You Think You Are?, where it was revealed that his maternal grandfather, David Yong Yee, immigrated to Sydney, Australia in 1896, becoming a prosperous banana businessman. In 1909, David and his family moved to Hong Kong where they were involved in the creation of the Chen Kwong company, a successful Chinese-Australian retail store and one of the first of its kind. The company was liquidated in 1925 due largely to the Canton-Hong Kong strike, where they returned to Sydney, Australia in 1938. His paternal great-great-grandmother, Elizabeth Wright, was born in Middlesex, England and arrived in Melbourne, Australia in 1853 as a domestic servant. Elizabeth married Fatt's great-great-grandfather, Lee Young, a hay and corn storekeeper in Ballarat with origins from Canton, soon thereafter. Lee and Wright later moved to Ararat in 1863, where Lee became a Chinese interpreter for the city's colonial court until 1873. The couple later returned and retired in Ballarat, with Wright dying in 1892 and Young dying in 1899. Their second youngest child of six, and Fatt's paternal great-grandmother, Emma, married Chinese Methodist missionary Joseph Tear Tack in 1885 and moved to Tingha until 1896, where they then moved to Darwin and was affected by the 1897 Darwin cyclone, being among the residents who lost their home. They later moved to Cairns in 1900. Joseph died a year later in August 1901 and was survived by Emma and their four children, who returned to Ballarat, then Burwood, before eventually settling in Concord West. Emma later died on 28 October 1948.^[4][20]

Health

In early July 2011, Fatt underwent heart surgery after feeling unwell for several weeks^[21] and having a blackout.^[22] He was diagnosed as having a heart arrhythmia and was fitted with a defibrillator at Sydney's Mater Hospital.^[21][22] His surgery was "urgent but routine" and Fatt was expected to recover completely.^[21] He missed the summer US tour as a result, after never missing a show in 20 years.^[22]
