Thanks, all, for the info.
Sandy, if you wouldn't mind posting the lyrics per G.B. I'd love to see them.
The tune I heard is pretty firm in my head, but I'm curious to hear what he has done with it. I am certain the song predates him. Of course, he may have worked with the traditional melody to make it his own.
I originally heard it as an encore in a baritone recital at Carnegie Hall, which also leads me to believe it's an older tune, since, generally speaking, only the older folk/Gospel material is used in "classical" repertory.
