Björn Ulvaeus is confident fans will be delighted with ABBA’s new music.

The Gimme! Gimme! Gimme! (A Man After Midnight) hitmakers first announced their reunion back in 2018, promising two new songs – their first in four decades – along with plans to hit the road with a new hologram tour.

While neither project has surfaced as yet, the band is still working behind the scenes to ensure the tour goes ahead.

Speaking to The Times, Björn opened up on the project, revealing the band were “photographed from all possible angles” and made to “grimace in front of cameras”.

“They painted dots on our faces, they measured our heads,” he recalled.

And when it comes to Agnetha Faltskog and Anni-Frid Lyngstad’s vocals, Björn admitted they had changed over the years, revealing they are “about one tone lower, perhaps” than in the group’s heyday.

However, he went on to promise that the sound fans would hear on the tour would still be “very much ABBA.”

Back in 2018, ABBA confirmed the release of two original new songs – I Still Have Faith In You and Don’t Shut Me Down – which has now been expanded to five, with Björn opening up on the direction of the tracks.

“One of them is a pop tune, very danceable,” he said. “The other is more timeless, more reflective, that is all I will say. It is Nordic sad, but happy at the same time.”
