When people tell me a Stevie Wonder joke, I ask them in return: who played the drums on most of Stevies records? Then they think it's another Stevie joke and they can't figure it out. Everybody thinks he's blind, except Stevie himself. Maybe he's just blind in seeing personal, musical and practical limits...
