Realising that some folks have used the word "tab" to refer to a set of lyrics with chords, rather than a full tab, I decided to tab this out for the guest. I first thought I'd better check Google to see if it was already available and found this: Van Ronk's Cocaine Blues

My brother and I learned to finger-pick from the album Dave Van Ronk - Folksinger in the early sixties. I had a chance to shake his hand and thank him for that before he passed.
