The legendary Swedish pop group ABBA is mulling a possible reunion next year, singer Agnetha Faltskog said in a German newspaper interview 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 subsequently became one of the world's best-selling pop bands with a string of number one 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.
Faltskog formed ABBA in 1972 with guitarist and songwriter -- and later husband -- Bjorn Ulvaeus, as well as Benny Andersson and Anni-Frid Lyngstad.
The band, whose last album "The Visitors" appeared in 1982, has sold more than 380 million records worldwide, making them one of the most successful pop bands in history.
