LISTEN TO ABBA TUNE 'WHEN I KISSED THE TEACHER' FROM MAMMA MIA! HERE WE GO AGAIN

Based on the hit Broadway musical of the same name, Mamma Mia! tells the story of Donna, an independent single mom who runs a hotel in Greece, and her daughter Sophie, who is about to get married. But Sophie wants to know who her father is—and after reading her mother’s old diary, sends wedding invitations to three of her mother’s old flames to find out which one is her dad. Set to the songs of ABBA, the movie stars Meryl Streep as Donna and Amanda Seyfriend as Sophie. The cast also features Pierce Brosnan, Colin Firth, Stellan Skarsgård, Christine Baranski, Julie Walters, and Dominic Cooper.

All will reprise their performances in the upcoming sequel, premiering July 20.
