Mamma Mia! It’s ABBA 2016

Much to everyone’s surprise, not only did Bjorn, Frida, Benny and Agnetha attend the opening of Mamma Mia! The Party at Gröna Lund in Stockholm on the evening of Wednesday 20 January 2016, but the four appeared together on stage, posing and waving (briefly, for about 20 seconds or so).
