Dave Grohl came close to arranging a collaboration between Weezer and Barry Manilow. The Foo Fighters frontman was keen to forge an unlikely pairing between the "Hash Pipe" rockers and the 69-year-old crooner for a track on his Sound City Studios documentary soundtrack and thinks the song could have been a hit.

"I was this f***ing close to getting them on a record. I thought it was going to happen. It would've been f***ing huge," he said.

The rocker admitted Barry was keen to take part in the project, but proved difficult to track down: "He was the first person who said he'd do it but was the last we tracked down. And we had to fly to f***ing Hawaii."

The documentary threw up several collaborations, including one between Dave, his former Nirvana bandmates Krist Novoselic and Pat Smear, and Paul McCartney.
