ABBA could be about to delight fans by reuniting for their 40th anniversary.
The group - made up of Agnetha Fältskog, Björn Ulvaeus, Benny Andersson, and Anni-Frid Lyngstad - are 'thinking about' marking the 40 years since they were propelled to fame at the Eurovision Song Contest in 1974.
Talking to German magazine, Welt Am Sonntag, Agnetha 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 teased.
While the Swedish group never officially split, they haven't performed together as a four piece since 1982.
All four members have resisted pressure to reform in the past, despite Benny and Bjorn working together on a number of projects together, including the musical 'Mamma Mia'.
At the 2008 premiere of the musical's film adaptation, they said there was 'simply no motivation to regroup'.
“We would like people to remember us as we were, young, exuberant and full of ambition,” Bjorn added.
ABBA notched up nine UK number one singles in the 70s and 80s and sold more than 380 million records worldwide.
