Foo Fighters frontman Dave Grohl agreed to a guest appearance on Slash's upcoming solo album after they bonded over chats during the school run.
The former Nirvana drummer and the ex-Guns N' Roses guitarist became friends after discovering their children attended the same school.
And Grohl admits their shared personal interests led to a professional collaboration on Slash's new self-titled record.
He tells Britain's Absolute Radio, "It's funny because his kids used to go to the same school as mine. So that's kinda how we met and started hanging out and so, you know, when your kids go to the same school as someone else's, the moms start asking the other moms for favours and it becomes a whole new thing. And he basically said, 'Hey, I'm making a record, do you want to sing a song?' And I said, 'No, I don't really want to sing - I'll play drums, though.'"
