The original logo that the band used for their first releases under the original name, ABBA-Teens

In 1998, Marie, Sara, Dhani, and Amit came together to form the ABBA-Teens and began recording their debut album which would consist entirely of covers of ABBA songs. Their first single, "Mamma Mia", was first released in April 1999 in their native Sweden where it stayed at number one for eight consecutive weeks. Following this release, the group's name was changed to the A-Teens to avoid litigation.^[3][4] "Mamma Mia" was released internationally following their name change and topped the charts in over ten countries.
