In case you don't remember the original Mamma Mia song by the group ABBA, watch here below:
ABBA (Benny Andersson, Björn Ulvaeus, Anni-Frid Lyngstad (Frida), and Agnetha Fältskog) perform their smash hit Mamma Mia.
What a beautiful song! Full of the funky energy of the 1970's! That's a song that really deserved to be adapted into a musical and then to be adapted to the cinema.
