Dave Grohl doesn't want your love

Dave Grohl is keen to stop rock stars being held in high esteem:

"We played a show recently for a bio-engineering company. We met the man who invented synthetic insulin. He basically saved millions of people's lives by reinventing that drug. He is the kind of dude who deserves a medal - not some drunk onstage wearing eyeliner and selling 10 million records.

"What we do isn't changing the world."

Hang about - weren't you on the Live Earth bill on the understanding that what you do can change the world?
