Just recently transferred my old cassette of this performance. It's not really any different or better than circulating versions by the way. I was going over it in some restoration software. I'm pretty confident that Makisupa Policeman was not performed from this date. Or that the Makisupa Policeman that commonly ends Side A is a filler or remnant of something else. Checking Phish.com it's not present. The frequency content is different and it sounds like it's recorded indoors. It's possible an early dub was taped over something else or that this was intentionally spliced on as a filler. Here is the newspaper clipping that helped figure out the correct date.
