Yes, the 1980 acoustic set renditions are super special and tasty.
I also love the 1976 early arrangement with the... more straightup mixolydian(? I think, just taking a stab) more major-y jam rather than the later dark Lydian craziness. 6/29/76 stands out in my mind as a really bright crispy one.
This song however, is one of the few imho that actually reached its peak in late 80's, stretching furthur than before, and going to some places of great power. Personal highlight: 7/15/88 (with the "T.J. Hooker" OctaPad sounds lol) ah, afternoon at the Greek!
