35 years since their last album, ABBA have announced that they will be reuniting to make new music.
A statement on the official ABBA Instagram page said: "The decision to go ahead with the exciting ABBA avatar tour project had an unexpected consequence.
"We all four felt that, after some 35 years, it could be fun to join forces again and go into the recording studio. So we did. And it was like time had stood still and that we had only been away on a short holiday. An extremely joyful experience!"
"It resulted in two new songs and one of them 'I Still Have Fair In You' will be performed by our digital selves in a TV special produced by NBC and the BBC aimed for broadcasting in December.
"We may have come of age, but the song is new. And it feels good.
"Agnetha, Benny, Bjorn, Anni-Frid - Stockholm, Sweden, 27 April 2018."
The reunion was also confirmed by the Swedish group's manager Gorel Hansen in a press release today.
The news comes a few days after singer and songwriter Bjorn Ulvaeus, 72 announced that virtual representations of the band - or 'Abbatars' - are being designed to represent the group on a tour that will take place in 2019 or 2020.
The virtual creations will show ABBA as they were back in their heyday during the 1970s. Bjorn said: "We thought we looked good that year."
"They photographed us from all possible angles, they made us grimace in front of cameras, they painted dots on our faces, they measured our heads,"
"Apparently a cranium doesn't change with age the way the rest of your body falls apart."
Over the course of their career the group sold more than 400 million records worldwide. They have not given a public performance since 1986 and their last album was 1981's 'The Visitors'.
Although the band never officially broke up they have endured a turbulent past. Anni-Frid and Benny, and Bjorn and Agnetha were previously married but both marriages ended in divorce.
It was thought that the band would never get back together. In 2014 Agnetha Fältskog gave an interview in which she said: "I think we have to accept that it will not happen, because we are too old and each one of us has their own life. Too many years have gone by since we stopped, and there's really no meaning in putting us together again.
"It's always nice to see each other now and then and to talk a little and to be a little nostalgic."
It looks like they'l be seeing a lot more of each other in the coming years.
