ABBA spark rumours of a reunion after Björn Ulvaeus teases new 'entertainment experiment' called Mamma Mia! The Party

It’s been a while since the last ABBA reunion rumour but following band member Björn Ulvaeus' mysterious reveal of a project called Mamma Mia! The Party, hopes have been raised once again.

"I've been working on this experiment for quite a while now and it's actually starting to feel ready', Ulvaeus said, according to The Local.

The website, titled Mamma Mia! The Party, features a teaser film which sees the 69-year-old star writing the project's name in blue paint.

While fans are crossing their fingers for a full group reunion, most think it could be a multimedia event or one-off performance.

ABBA saw their popularity skyrocket after winning the Eurovision Song Contest for Sweden in 1974 with Waterloo, and went on to have a string of international hits before breaking up in 1982.

Since the band's demise, Agnetha Fältskog and Anni-Frid Lyngstad have pursued solo careers, while Ulvaeus and Benny Andersson have penned the stage hit Mamma Mia!.

The musical, which features over 20 hits from ABBA's back catalogue, has grossed over $600 million and spawned a Hollywood film featuring Meryl Streep.

It was announced last week that Mamma Mia! will be performed for the last time on Broadway this September.
