Pete Seeger has a go at this. He says he can’t play it like the one who wrote it, and he’s right.
If Joan Baez sang her grocery list, I would sit and listen to that. But she probably also takes the easy way out playing this song.
It was written in the 1900’s by Libba Cotten, who played guitar upside-down like it’s the only natural way. He singing voice is not really charismatic, but oh! that guitar.
