same year. In 1998, an ABBA tribute group was formed, the ABBA Teens, which was subsequently renamed the A-Teens to allow the group some independence. The group's first album, The ABBA Generation, consisting solely of ABBA covers reimagined as 1990s pop songs, was a worldwide success and so were subsequent albums. The group disbanded in 2004 due to a gruelling schedule and intentions to go solo. In Sweden, the growing recognition of the legacy of Andersson and Ulvaeus resulted in the 1998 B & B Concerts, a tribute concert (with Swedish singers who had worked with the songwriters through the years) showcasing not only their ABBA years, but hits both before and after ABBA. The concert was a success, and was ultimately released on CD. It later toured Scandinavia and even went to Beijing in the People's Republic of China for two concerts.

In the same month, American singer Madonna released the single "Hung Up", which contains a sample of the keyboard melody from ABBA's 1979 song "Gimme! Gimme! Gimme! (A Man After Midnight)"; the song was a smash hit, peaking at number one in at least 50 countries. On 4 July 2008, all four ABBA members were reunited at the Swedish premiere of the film Mamma Mia!.
