Dave Grohl has suggested Foo Fighters could make a follow-up to their Sonic Highways documentary, according to Digital Spy.

The original series followed the band as they recorded their new album in eight U.S. cities, interviewing key figures in music along the way.

"There might be a season two," Grohl told Billboard. "There are a lot of studios."

The frontman suggested Foo Fighters could travel to the UK and spend time at Abbey Road Studios, where The Beatles recorded most of their albums.

"If we went to somewhere like Abbey Road it'd be fun to interview someone like Paul McCartney or George Martin. That'd be kind of cool," said Grohl.
