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". The plot follows a young bride-to-be who invites three men to her upcoming wedding, each one with the possibility of being her father.
