Story Behind The Song

I was watching TV and Eric Clapton was on by himself doing some Robert Johnson stuff. Never composed in that genre but it sounded kinda interesting. The BG said " why the fuck not?" So I gave it a shot. The BG had given me the opening lick 10 songs ago but I couldn't come up with anything else I liked. Thought it was headed to the Twilight Zone of unfinished work, then SRV came by in a dream and gave me some ideas for a direction.
