The fans could hardly believe their eyes! All 4 of the ABBA members arrived at Cirkus theater to enjoy the Swedish production of Mamma Mia!
All four went to the after party. Agnetha was rumored to have left in a hurry, but she didn't leave nor was it in a hurry. Frida and Agnetha were seen hugging and talking afterwards and all 4 went back to congratulate the cast.
