Blind musicians

I was listening to a radio programme for the blind the other day and it struck me that there have been some wonderful blind musicians - especially in the blues field - over the years. Ray Charles and Stevie Wonder spring to mind of course, along with the great Clarence Carter (pictured at Jazzfest 2010), but many of the influential early blues singers were blind. They include Blind Lemon Jefferson, Blind Willie McTell, Blind Willie Johnson, Blind Boy Fuller, Blind Mississippi Morris and Blind Blake (not exactly hiding their disabilities of course). And then there was Sonny Terry, Little Buster and the partially sighted Sam Myers and, more recently, the late Jeff Healey.
In the jazz field there were Art Tatum, George Shearing, Diane Schuur and Roland Kirk, and in pop Al Hibbler (who had the original hit with Unchained Melody), Jose Feliciano and Ronnie Milsap. In the gospel field the Blind Boys of Alabama and their Mississippi counterparts stood out, as did the Rev Gary Davis. From reggae there's Frankie Paul and from New Orleans there's pianist and singer Henry Butler (pictured at Porretta in 2008).
No doubt there are others and I would be interested in any suggestions.
