I didn't want to mention this, but no one else has. I avoided posting it because it makes an accusation. I'm sure that there are lots of people who know something about the extent that the accusation is true, but I'm not one of them.

At any rate, there is a song verse which is supposedly by Leadbelly, although it may be apochryphal. It goes:

If anybody should ask you who wrote this song
Tell them Huddie Ledbetter's been here and gone
If anybody should ask you who copyrighted this song
Tell them it was John Lomax and his goddam son
