Thank you all for this lively percussion. Richard Bridge, I don't know if this is a "problem" As a Bluesman I have always had a fascination with the history of songs and how they came about. I remember this Dock Watson vinyl (title escapes me) The last song was "Tom Dolley" and the half of the liner notes were the history of the song and who was related to who and how. I am sure the Lomax family expended a great deal of time on this subject as they were cataloging their songs
