Brother John Sellers
UPDATE: I think this is the album Joe suggested in class. Sonny Terry is not mentioned in the discription but it sounds like him to me. What do you think?
Brother John Sellers "Jack of Diamonds" Album. It doesn't get any more real than this!

Definitely sounds like Sonny Terry to me, or, a very good impersonator.
