Swedish pop legends Abba have recorded their first new material in 35 years.

The band says they’ve got two new songs in the bag. One of them, ‘I Still Have Faith in You’, will be released in December as part of a TV special in which the band will perform as holograms.

“The decision to go ahead with the exciting Abba avatar tour project had an unexpected consequence,” the band said in a statement.

“We all 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 we had only been away on a short holiday. An extremely joyful experience!”

Abba sold millions of records, not just in their 1970s heyday but for decades after their split in 1983.
