ABBA have reunited in London to film content for their forthcoming hologram tour, according to new reports.

The iconic Swedish pop group first teased plans to release new music hit the road with a hologram show back in 2018, but so far the comeback has yet to come into fruition.

According to The Sun, however, Agnetha Faltskog, Bjorn Ulvaeus, Benny Andersson and Anni-Frid Lyngstad recently got back together to film at Ealing Studios in west London for the jaunt.

An insider shared: “ABBA have kept everything about their reunion shrouded in mystery but this has really been a long time coming… although it’s been a slog to get to this point, it is now full steam ahead and the show is taking shape.

“Agnetha, Bjorn, Benny and Frida have all recorded bits and pieces and they have enjoyed taking a trip down memory lane with it all,” the source explained. “They are all getting a nice cheque out of it, so it will be worthwhile, but they’ve got more than enough money from their music, so it’s not about that.

“All four of them just wanted to give back to their fans, so they have done everything in their power to fly into London for the filming, despite the travel restrictions.”

The show will apparently feature five new songs, which are expected to be released next year (21) — 38 years after their last UK single, Under Attack. Titles for two of the new tracks have been confirmed as I Still Have Faith In You and Don’t Shut Me Down.

According to the report, the group had been offered $1 billion to reunite and tour in person, however they turned down the deal.
