I'll try my best to get the TAB finished. I've never posted TAB here, so I'll look into that first. I play it a bit differently than the way it's transcribed in Ainslie's book. I suspect, Johnson himself played it differently each time he performed anyway. Also, Johnson does not use a slide in this piece. He plays it more like a straight 12-bar number. Personally, my favourite Robert Johnson slide piece is Come In My Kitchen which is in Open G (or A). Anyway, I really will try to get the TAB transcribed and posted.
