I am remastering (and consequently listening) 6/19/1972, shame about the recording!

Orlando 8/31/71 is a candidate for best version for me. I also like a lot the 1980 versions in particular due Jonesy's CP 70 with gives a prophetic atmosphere to the song. The Brussels 6/20/80 one is obe of the best (and the show itself is my favourite 1980 show)
