Cathy, I just came across your post regarding Keep Your Hand On The Plow ( I've been looking for written lyrics for over a year) Anyway you asked about the origins. I don't know too much about it but you can hear a fabulous rendition of it on the album: Mahalia Jackson: Live At Newport 1958. She does that number with Duke Ellington and his orchestra. The album is Columbia Jazz Masterpieces. You should be able to get it from something like BMG Jazz Club or order it from a good musc store. Hope this helps.
