On his debut Vanguard album (vintage 1960's), Doc Watson sings the most authenic version of the song that I've heard. The liner notes also tell much of the story. Sheriff Grayson was, indeed, a major part of the story, which is very much as Barry Finn tells it. I had heard the song sung many years before by my Granny (who was from West Va.) and when the Trio came out with their version I thought it was just a different song entirely. Either version is a pleasure to listen to, however.
