Foo Fighters rocker Dave Grohl has performed drunk for the last 15 years, because sobriety onstage leaves him anxious and uptight. The singer confesses it takes a lot of alcohol for him to loosen up and enjoy himself at gigs.

He says, "Yeah, but not in f---ing 15 years. When you play sober, you're hyperaware of everything going on, whereas nonsober shows are fun because you don't give a f--k -- it usually turns into a blood-and-public nudity display."
