Pascal, I don't know if you noticed them but on the tab were links to a couple of SoundClick audio-things where I tried to explain a little as I went along which may (or may not!) help make it a little clearer. Anyway I hope the tab works for you.
(By the way, I can do the same sort of thing for "Police Dog" if needed. Yeah, that was a real tough one for me too. Even with John Jackson's help. (He played it flawlessly, having learned it from Blind Blake's "leader-boy" when he was young.) I worked with it off and on for a long time. He always said someday it would just sort of "fall into place" for me and I'd be playing it. He was right. Of course I can't play it like Blake or him, but I do pretty fair. I also add a few licks and runs of my own while still trying to keep it pretty authentic to Blake's style and using his theme-licks. Someone had also asked me for "Diddie Wah Diddie" before. I started to tab it, but finally just decided it would be better and easier if I just did it as a four-part SoundClick audio-thing. Another good Blake-tune. Not too easy a tune, but I think quite a bit easier than Police Dog.)
Funny when you think about it... Someone like me or you, we work and work on a tune like that for a long time and even have help like tabs or someone else helping us, etc. And we still can't come close to being able to play it like he did. And he started with just an idea, wrote it and played it to perfection (and was blind yet!). Yeah, no question about it, Blake was a true master.
I've liked quite a few VanZandt tunes. I used to do "Poncho and Lefty" sometimes, that being one of his more popular ones if someone requested something by him. I liked his version of the tune "Dead Flowers" (the Stones' tune). Someone told me once that it was actually originaly a Townes VanZandt tune that he used to do, and that the Stones while on a tour caught one of his shows in a little club and recorded it as their own. (They had a history of doing that. Going into little clubs and finding some "nobody" doing a great tune and then "borrowing" it as their own!

) (A couple others I can think of off hand were "The Last Time;" "It's All Over Now" and "Prodigal Son" where they were eventually forced to credit the original authors.) Anyway Van Zandt never copyrighted it or anything, and while he did have some evidence like old tapes, etc, that he'd been playing it long before the Stones published it, he didn't wanna go through the hassle of trying to sue and all that (probably never sober long enough

), but he made it a point of playing it frequently at his gigs after that.
