The quartet’s two new songs are due for release later this year, after Agnetha Fältskog, Björn Ulvaeus, Benny Andersson and Anni-Frid Lyngstad reunited in the studio.
They said in a statement: "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!"
They continued: "It resulted in two new songs and one of them I Still Have Faith 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.”
The statement - issued to the band’s Instagram - was signed off from all four members and published today from Stockholm, Sweden.
