A few years ago, there were a number of musicians who performed and chatted on stage with Les Paul - most of the videos are on YouTube. The one with Billy Gibbons was pretty good - during the banter portion, Les asked Billy if he ever got the urge to shave it off. Billy responded that he was afraid to see what was under there, now. Understandable, he and Dusty Hill have been bearded since 1979 or so - pre-MTV.
I always thought it was hysterical that the guy with very little facial hair is the one named Frank Beard. LOL.
