Sorry Bub, as much as I like Lou Reed, his versions sucked.  I'm glad that they devoted so much time to Skip James.  I've got a video of him, Bukka White, Son House, Muddy Waters and a few others playing in a backroom bar at Newport '64.  The section on J.B. Renoir was great too.  I hadn't heard of him before.  I'll have to check him out.
