Michael Buble may have joined the Foo Fighters live on stage following an ongoing joke, but it seems Dave Grohl is not keen to add him to the band’s permanent line-up.

The group, fronted by Grohl, 54, has been performing a medley of hits on tour including Buble’s “Haven’t Met You Yet”, and have invited a fan on stage to join them sing it at each concert. At Outside Lands, Buble himself got up on stage after pretending to be a fan in the audience.

Buble had even more fun with the joke after the set as he informed fans on X he’s been invited to join the Foo Fighters.
