ABBA reunion in Stockholm for 50th anniversary party - PHOTOS

Agnetha Faltskog, Bjorn Ulvaeus, Benny Andersson and Anni-Frid (Frida) Lyngstad appeared in public together for an impromptu ABBA reunion on Sunday, June 5, for a celebration to mark the half-century since the legendary pop group was born.

The Swedish stars were invited to a private party at the Berns Salonger hotel in downtown Stockholm, according to the "Expressen". According to some fellow guests, ABBA shared a musical moment - something that hasn't been not for decade. Images of the former bandmates singing and embracing on stage have been circulated on social media though video of the performance has yet to emerge. 

ABBA split in 1982 and hasn't performed together since 1986; they sold more than 380 million albums worldwide in a career that exploded in 1974 with its Eurovision Song Contest-winning performance of “Waterloo”.
