Though the world premiere of the film occurred elsewhere, most of the media attention was focused on the Swedish premiere, where Anni-Frid Lyngstad and Agnetha Fältskog joined Björn Ulvaeus and Benny Andersson with the cast at the Rival Theatre in Mariatorget, Stockholm, owned by Andersson, on July 4, 2008. It was the first time all four members of ABBA had been photographed together since 1986. "Mamma Mia! Here We Go Again"
Mamma Mia! Mamma Mia! Mamma Mia! (promoted as Benny Andersson & Björn Ulvaeus' Mamma Mia!) is a jukebox musical written by British playwright Catherine Johnson, based on the songs of ABBA composed by Benny Andersson and Björn Ulvaeus, former members of the band. The title of the musical is taken from the group's 1975 chart-topper "Mamma Mia". Ulvaeus and Andersson, who composed the original music for ABBA, were involved in the development of the show from the beginning. Singer Anni-Frid Lyngstad has been involved financially in the production and she has also been present at many of the premieres around the world.
