FOO FIGHTER DAVE GROHL is fixated by late BEATLE John Lennon because he can't imagine how one person could be such a contradiction.

The former NIRVANA star regards the IMAGINE hitmaker as the ultimate role model, but remains bemused by his muddled legacy.

Grohl is especially interested in the peace campaigner's well-documented violent streak.

He says, "I always heard Lennon was the bruiser who didn't mind a punch-up now and then. I thought that was pretty cool seeing how he was the peace-and-love guy.

"He was a f**king saint but he seemed like he could be a criminal which I really like."
