Dave Grohls pre-Foo ritual?

Dave Grohls pre-show ritual before a Foo Fighter show?

A can of Budweiser...an hour before he hits the stage..several shots of Jagermeister--which he calls "RockQuil"...and then minutes before he hits the stage he'll suck up one last Parliament Light, take 2 swigs of beer, and follow that with 3 tablets of nicotine gum.          

Grohl says he's never taken coke, heroin or speed.  He jokes he'd be ridiculous on amphetamines, because he doesn't shut up as it is.
