Putting aside the question of how my mind works for a moment, having made a list of blind musicians recently I thought we might have one of deaf ones. Unsurprisingly there are far fewer. The percussionist Evelyn Glennie and perhaps Beethoven are the only real contenders. Or have I missed someone?
As for the one armed there is Paul Wittgenstein (brother of the philosopher) and Rick Allen the drummer with Def Leppard. Any more?
