Paul Shaffer can't read music - That was the astonishing conclusion to this interview I heard on NPR's Morning Edition. David Letterman's bandleader has a new autobiography coming out and he revealed his rise from piano player at a topless bar in Canada to late-night troubadour. What was hilarious about the interview was that Shaffer threw it out, almost as an afterthought. The guy learned to play by ear and he's managed to make to the top.
