ABBA have reunited for the first time in eight years. The Swedish pop group made a public appearance together in Stockholm for the first time since the 2008 launch of movie 'Mamma Mia!' - a film based on their successful career - when they attended the opening of a new restaurant, aptly-named Mamma Mia! The Party. But band member Benny Andersson confirmed it is unlikely the foursome - also made up of Agnetha Fältskog, Björn Ulvaeus, and Anni-Frid Lyngstad - will ever return to the stage together. Björn told reporters they just wanted to have fun, adding: "We are here to party." Last year, he insisted the band won't ever reunite for a performance because they don't need the money. He said: "We took a break in '82, and it was meant to be a break. It's still a break and will remain so. You'll never see us onstage again. "We don't need the money, for one thing. Usually the reason bands have reunions is that one of them is destitute and the others want to help. Fortunately that has not happened to us." ABBA were formed in Stockholm in 1972 and went on to sell more than 380 million records after winning the Eurovision Song Contest in 1974 in the UK with their song 'Waterloo', which went on to top the charts in 10 countries.
