I got John Hurt's autograph and shook his hand in some club in DC in '64 - when I got back to my seat, I noticed that Libba had been standing next to him - so I didn't get her autograph. But I did see her later at the Old Town School and have always played "Oh, Babe," which I must have learned at the OTS.
Carolyn Hester had a nice recording of that song, but it might sound a little dated now. I think Bob Gibson also had a version.
I think she said that she wrote the song as a child when some neighbor was gossiping about her.
