As mentioned above, Blind Willie Johnson recorded this song, along with a woman singer named Willie B. Harris, during his fifth recording session, which was held in Atlanta on April 20, 1930. There may be an earlier recorded version, but if there is I've never encountered it. I think Rev. Gary Davis and a few later players may have covered it, but I'm not sure. I know Davis did cover a lot of BWJ's stuff and I've run into a lot of people who think his versions are the original. I found some gratification in knowing Davis (whose work I admire, but don't particularly like) was doing bad copies of a much greater talent's stuff.
