I like Rev. Davis. As I've said, I was lucky enough to go to U.C. Berkeley in the 60s when all manner of musician and other artists were around. I heard blues on record players and live from real blues players. I had musician friends who played Blues licks. Of course, they couldn't sing them worth anything. (I'm being careful about my four letter words because I had a long post excised for using a four letter word.}
I must explain, though. I have a dry sense of humor and posting a spiritual by a guy who looked like John Denver was slightly pulling your leg. That's not to say I wasn't taken by him when I heard him on the radio. And I still like that song.
The old blues and spirituals sounded dated, though, in the 60s and 70s. I think my spiritual singers were Marvin Gaye (What's Going On) and Stevie Wonder. I can't imagine that anyone on this thread hasn't heard "What's Going On." If you haven't heard it either run out and buy the album or stream it.
