Not music, but a few years ago at the Golf Club I was a member of, I used to play occasionally against a man who had only 1 leg. If I remember correctly he had a handicap of about 22.
He used a crutch to support one side of his body and used his one arm to hold the crutch. The other arm, he used for holding the golf club.
He was an incredible guy and it was amazing to watch him play some unbelievable shots.
Such a nice man.
