This was possibly one of the weirdest shows I ever saw (but enjoyable nevertheless). It took place on a Weds about 2:30 in the aft (if memory serves). I'd heard it promoted on wnew-fm the day before, so I rounded up at least 10 of my regular deadhead friends and we went to what turned out to be a giant, ornate, old movie palace behind the el in Brooklyn. The theater was basically deserted. We sat in the third row. (I think the band just wanted to rehearse in a big theater(?) because Phil would put down his bass and run around the auditorium, apparently doing sound checks.) Anyway, we were literally half of the audience until a few songs in when a whole group of senior citizens (at least 20) filed in and sat a few rows behind us (not your usual dead crowd!). The 10+ of us noticed them, but didn't know what to make of their presence, so we just carried on as usual (if you know what I mean). Bur for years I wondered what drew them to see the dead? A few years ago, still wondering, I told this story to a dead head who grew up in Brooklyn and he knew the answer. They were from a local senior citizen home and they were on an outing. They had no idea what they were walking into, but the theater had a package deal with the home to get them out and about, and that must have been one of the days they were scheduled to go to that theater to see a movie. They didn't come to see the dead, (but I wonder what they made of them). By the way, the show was pretty good. It must have been because the old folks stayed for the whole thing (or else, weird as it must have been to them, it was better than going back to the home). -Reg the Veg**update 20150815 to cross reference LIA's post, posting text of a Variety review (see reference below) and LIA's usual amazing commentary.
