Thanks for the feedback guys! I like the breakout slide part also and think the classy ending decription is spot on - he was indeed an elegant player.
Going into the song I naively thought because it was basically a 1st position E and A chord song it wouldn't take me very long to work it out - boy was I wrong! Besides the chords, everything about this song to me is hard here is a partial list: the rhythms of the E chord are difficult to play let alone sing, ditto the A chord arpeggio. The vocal intervals are unfamiliar and hard to hit. The sliding part has odd timing that I landed only after counting the slides and associating the start of the slide with specific words in the verse. Although I think I play the same chord progression he does at the end, in order to not break time, I had to shorten it by a couple beats leaving out the 6th string walk he does before playing those "classy" breakout chords at the end of the song. I never did nail the turnaround. What I ended up with (to my chagrin) is really more of an impression than a cover. My favorite blues tend to be the harmonically simple and rhythmically complex songs. This one fits that bill and certainly stretched me to my limits.
