Swedish pop group Abba is mulling over a reunion next year, singer Agnetha Faltskog said in a German newspaper interview on Sunday.
Next year marks the 40th anniversary of the band's first hit, Waterloo, which won them the Eurovision song contest and catapulted them to fame.
Abba became one of the world's best-selling pop bands with a string of No. 1 hits such as Mamma Mia, Dancing Queen and Super trouper.
"Of course it's something we're thinking about," 63-year-old Faltskog told the weekly Welt am Sonntag.
"There seem to be plans to do something to mark this anniversary in some way. But I can't say at this point what will come of them," she said.
