I saw him in Georgetown Va in'76. Drove up there the day before for the Bob Marley concert at the University Gym. We were strolling the common area and he had a small sign out side a little cafe. He was alone with 2 reel to reels. He's wail some riffs, play it back while adding to it on the other RtR. He was able to play the recordings backward and add to those. Pretty spacy.

If you ever went to the Mex E Cono Restaurant on the OBoNC in the 90's, I gave them some cassettes and all of them had to have this song beginning each side.
