In a new interview with The Daily Beast, producer Butch Vig speaks on several topics including a project that never came to be. Vig says while he did once turn down an opportunity to work with the Rolling Stones, he is particularly bummed that a project involving Dave Grohl, Krist Novoselic and Neil Young never came to fruition.

“It would have been fucking awesome. And I know if Neil Young played with them he’d go, oh, let’s go on tour and play some shows together! It would be like Crazy Horse on steroids,” Vig said. “Neil Young had a book coming out so he was on a book tour, and Dave had to go interview him somewhere else. It’s a bummer, man.”

The project would’ve been a part of Grohl’s Sound City film that saw him team up with the likes of Paul McCartney, Trent Reznor, Stevie Nicks, Josh Homme and many others throughout the film. McCartney ended up actually fronting Grohl, Novoselic and Pat Smear for a new song dubbed “Cut Me Some Slack” which earned the group a Grammy award.

Vig, who is currently promoting an upcoming film The Smart Studios Story about his Madison, WI studio, also gave an update on the Foo Fighters, saying, “I just met with Dave and he’s been writing some songs, but there are no plans for more Foos. I know he talked about another Sonic Highways, but nothing’s come to fruition yet.”
