They're one of the best and most iconic pop bands of all time, but ABBA have never reformed since splitting in 1982.
In a way, you have to admire their integrity for doing so - but a 'virtual reality' reunion and tour that was touted earlier this year is coming to fruition and should be on the road by 2019, according to Benny Andersson.
Andersson appeared on ITV's Lorraine yesterday to discuss both the tour and Mamma Mia 2 - and he also spoke about the reasons behind the band's split and why they never got back together.
"Things were happening in real life too, not just in [our] working life," he said. "[Anni-Frid Lyngstad and I] got divorced, [Björn Ulvaeus and Agnetha Fältskog] got divorced. At first we still worked together though because we knew what we had."
He added that the break was supposed to be temporary until he and Bjorn Ulvaeus were approached by Tim Rice to write musicals - including 'Chess'. "We were on a break when Tim came along," he said. "He gave us these opportunities and afterwards, we were like what's the point in going back, because we like theatre so much?"
Of the 'virtual reunion', he said: "If everything goes to plan, we will be back in digital form at the beginning of 2019. Ot is going to be a virtual tour but everything will be live.
"It will be as though we are out on the road because the whole set-up is live. It will just be us four singers that are in digital form."
A good or terrible idea? We'll have to wait and see...
