Actor Jack Black stunned fans at the Foo Fighters concert in Auckland on Saturday night with a surprise performance of an AC/DC classic.

The actor, currently in New Zealand to film the Minecraft movie, was introduced by Foo Fighters’ frontman Dave Grohl at Saturday’s concert.

Grohl told the audience at a packed Go Media Mt Smart Stadium that he couldn’t leave without singing an AC/DC song, but that he wouldn’t be singing it himself.

Seconds later, Black, wearing a shirt emblazoned with a phoenix and sporting a pounamu around his neck, came bounding onto the stage to cheers from the crowd.

He then sang the song Big Balls off the Aussie band’s 1976 album Dirty Deeds Done Dirt Cheap with Fiona, the Foos’ own drum technician, later commando rolling off stage as the song finished.

Earlier in the show, Grohl had reminisced about the band’s “seismic” show at Western Springs in 2011 where Tenacious D was a supporting act.

Footage of the Kung Fu Panda star’s surprise performance spread quickly on social media, with fans expressing disbelief at his performance.

“I couldn’t stop shock-laughing at the wild Jack Black appearance at the Foos,” said one attendee on X.

“High energy, rolly pollies – no notes.”

Saturday’s concert was the first of three by the Foo Fighters in New Zealand this month.

It was also their first New Zealand concert with new drummer Josh Freese.

The shows were initially scheduled for December 2022 but were cancelled following the death of drummer Taylor Hawkins in March of that year.

The Foo Fighters, joined by opening acts Dick Move and The Breeders, will be playing at Apollo Projects Stadium in Christchurch on January 24, and at Sky Stadium in Wellington on January 27.
