I feel honour obliged though to point out that it was written by Bessie Smith, not by Leadbelly. I once got into a long tizwaz with a trombonist who announced to an audience that Leadbelly wrote it and made the original recording, and that it was subsequently covered by Bessie.

When I pointed out that Leadbelly didn't record his version until some seven years after Bessie died, he said "Oh I just make them up as I go along".

He then added that I was the first person who'd ever taken him to task over anything he ever told an audience. Oh well.
