If you are a baritone, as most of us are and can sing a note, then surely you have spent untold hours singing along with Doc. As for accapella singing -- "Blues Stay Away From Me", jumps out because of his impeccable pitch and rock steady delivery. I wish all of his songs were put out in sheet music, because I would own every one, probably multiple copies.

Ditto to all of the other deserving compliments heaped on a man who seems completely unbothered with the praise.
