Oh, Jeri, Bill got the "Massa of the Sheepfold" from my mother who got it from one of our summer visitors Wendy Holt, back in the 1940's. Art Thieme has posted some excellent notes on the song, and I've also found it in a 19th century collection of poems entitled "Heartrobs." I didn't dare try to sing it at the memorial service, or the "Ten Thousand Welcomes."
