For the new show, digital versions of ABBA were created using motion-capture and performance techniques by the four band members and an 850-strong team from Industrial Light & Magic.

The company, which was founded by George Lucas, is famous for creating the SFX for numerous Star Wars and Marvel blockbusters. This is the company’s first foray into music.

Bjorn said: “We did motion capture in a studio that looks like NASA. We were there for five weeks in leotards with dots on our bodies and helmet and then the four of us were on stage doing these songs…

“We looked ridiculous but we have really infused ourselves into these avatars.”

Benny added: “The only big problem was we had to shave our beards. After 40 years!”
