Blind Musicians

I have great respect for Ray Charles. Anyone who could seriously try to tell the IRS that he didn't have to pay taxes because he was blind has two huge brass ones hanging. And anyone who could drink a half a mug of gin and a half a mug of coffee has my respect. But I'm curious about other blind musicians. For example, if you've ever seen a Stevie Wonder video, you have to question whether he dresses like that for the effect of the show or because the people working for him don't think they get paid enough. Some of the costumes are just nutty. At least nutty enough for me to believe that Elton John is probably blind too.
