"Mamma Mia" is a song from ABBA's 3rd album, ABBA, written by Benny Andersson, Björn Ulvaeus & Stig Anderson, with the lead vocals shared by Agnetha Fältskog and Anni-Frid Lyngstad. The song's name is derived from Italian, where it is an interjection (literally, "My mother"). The song is about a woman who is time and time again disappointed by her unfaithful partner, but forgives him anyway.
