"Mamma Mia" is a song from ABBA's third album, ABBA, written by Benny Andersson, Björn Ulvaeus & Stig Anderson, with the lead vocals shared by Agnetha Fältskog and Anni-Frid Lyngstad. The B-side of the single was the instrumental "Intermezzo No.1", also included on the ABBA album.
Mamma Mia was A*Teens' debut single from the album The ABBA Generation. The song is a cover version of the popular hit by ABBA.
When the single came out in the spring of 1999, it became a smash hit in their home country, Sweden, where it peaked at number-one and stayed there for eight consecutive weeks earning a platinum certification.
On the initial pressings of the single, the name of the band appeared as ABBA*Teens, but Universal Music thought it would be better to change the name of the band to A*Teens so the new pressings of the single were made.
The single hit Top Twenty in almost every European country, reaching number-three in Norway, number-nine in Switzerland & Netherlands, number-ten in Germany, number-twelve in the United Kingdom, number-fourteen in Austria and Finland, among others. A Spanish version of the song was recorded for promotion in Latin America and Spain.
Despite the worldwide success, the song failed to attract the Australian public, peaking at seventy-two on the ARIA Charts. The album flopped and the A*Teens stopped releasing singles/albums in that country until the 2002 single "Can't Help Falling In Love". "Mamma Mia" also peaked at thirteen in New Zealand, but due to the lack of success in Australia, the further singles were never released in that country either.
In the United States the single peaked at sixty-three on the Billboard Hot Single Sales Chart, becoming the band's first single to chart in the country.
