Swedish pop group ABBA have made a rare joint appearance, but refused to pose photographs at the opening of a Stockholm restaurant inspired by the Mamma Mia! musical.
Benny Andersson, Agnetha Faltskog and Anni-Frid Lyngstad showed up Wednesday for the opening night of fellow former band member Bjorn Ulvaeus' Greek taverna, where guests are invited to sing along to ABBA tunes.
They did not sing or pose for photos together and rejected suggestions they would ever perform together again, with Andersson saying "I don't think so."
However, an image of the four together was posted on the band's official Facebook page.
The restaurant, where musicians and actors interact with waiters and guests, has borrowed the Greek-island setting from the Mamma Mia! musical and movie, but Ulvaeus said "it's a completely different story."
The iconic band, who rose to fame in the 1970s and won the Eurovision Song Contest in 1974 with Waterloo, are reported to have sold more than 375 million records. They made their last public appearance as a group in 1982.
