2014 marks the 40th anniversary of Abba's very first hit "Waterloo," which gave the pop group a win in the Eurovision song contest and led them into international fame.
Abba followed up the win with a string of number one hits, including "Mamma Mia," "Dancing Queen" and "Super Trouper" which made them one of the world's best-selling pop bands .
Talking to the German weekly, Welt am Sonntag
(German language), 63-year-old Fältskog said, "Of course it's something we're thinking about."
"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 added.
in the interview that she doesn't want too much notice of a possible future reunion, as it would be too stressful to plan. She prefers that the event just happens: "Not think about - just do it."
She did admit that age plays a role in future plans, saying, "We're all getting older, I cannot imagine that we would go on stage with crutches."
In was in 1972 that Fältskog formed the group Abba together with guitarist and songwriter, later, husband. Björn Ulvaeus, along with Benny Andersson and Anni-Frid Lyngstad. It was two years later that they achieved success in Eurovision with "Waterloo" in Brighton, England.
The last album released by the band was The Visitors
back in 1982, which has sold more than 380 million records worldwide. This, together with their other well-known hits, makes them one of the most successful pop bands in popular music history.
Both couples that made up Abba have since divorced, and after the band broke up, Fältskog has been releasing solo CD's, most of which reach the top 10. After a 10-year break, she has released her new album A
(Universal) in the spring. On November 22 it will be released in a deluxe version, and will include a one-hour DVD documentary "Abba and after".
Talking of the band, Fältskog said, "I dream often of late about the other three members of Abba. They are good dreams. Abba is a big part of all of us, still."
