ABBA

ABBA ( AB-ə [ˈâbːa]) were a Swedish pop group formed in Stockholm in 1972 by Agnetha Fältskog, Björn Ulvaeus, Benny Andersson, and Anni-Frid Lyngstad. They are among the most renowned and commercially successful musical groups in history.

In 1974, ABBA won the Eurovision Song Contest for Sweden with their song "Waterloo". In 2005, "Waterloo" was chosen as the best song in the competition's history during its 50th anniversary celebration. During their peak, ABBA comprised two married couples: Fältskog and Ulvaeus, and Lyngstad and Andersson. As their fame grew, their personal lives suffered, leading to the dissolution of both marriages. These relationship changes were reflected in the group's later music, which featured darker and more introspective lyrics.

After ABBA disbanded in December 1982, Andersson and Ulvaeus continued their success writing music for stage, musicals, and films, while Fältskog and Lyngstad pursued solo careers. Ten years after the group's breakup, the compilation ABBA Gold was released and became a worldwide best-seller. In 1999, ABBA's music was adapted into Mamma Mia!, a stage musical that toured globally. As of October 2024, it remains one of the ten longest-running productions on Broadway (closed in 2015) and the West End (still running). A film of the same name, released in 2008, became the highest-grossing film in the United Kingdom that year. A sequel, Mamma Mia! Here We Go Again, was released in 2018.
