There was a time when it would have been Stephen Lawrie of The Telescopes. He just had one of those faces!
Otherwise, smug twats like Chris Moyles, Nicky Campbell, Cliff, Phil Collins, Sting, Will Young, or rock bores like Clapton, Geddy Lee, Dio, Coverdale, Dickinson, Greg Lake, Jon Anderson, Steve Howe, that Biff Saxon bloke, Roger Waters, etc, etc.
Oh yeah, and anyone who suggested Morrissey here!!
