Here's the ones I use, drawn basically from the Doc Watson version.(/****/ is one measure)
/Dm7 Am7/Dm7 Am7/Dm7 Am7/Dm7 Am7/
/Gm7 /Gm7 /A7 Bb7/A7 /
/Dm7 Am7/Dm7 Am7/Dm7 Am7/Dm7 Am7/
/F Dm/Gm7 A7/Dm7 Am7/Dm7 Am7/
I play this one with the capo on the second fret so it sounds in Em (better for my voice). I also play a harp break on it with a Lee Oskar D natural minor, which makes it sort of in an E dorian mode. All the notes are there. Being from the vicinity of Charleston we always considered this a local tune. I'm glad it's being appreciated in other places.
Good luck, Chet
