I believe they played until about 8pm!! That UCSB concet was such a mellow event from start to finish: after standing on line for maybe an hour in the morning, they simply let everyone walk down the road leading to Campus Stadium and just walk in where ever they wanted to go. Everyone could simply set up blankets on the field in front of the stage, beach chairs, picnic, whatever. As I described above, after listening to who I thought was Zevon at the farthest point in the stadium away from the stage, when the Dead started playing, I was able to casually walk right up to the chainlink fence in front of the stage - maybe 30’ or so in front of and just to the right of Jerry - where I stayed for the whole time. In fact, check out this [photo]. If you look at that photo, in the very bottom corner on the right is the top of someone’s head: that’s exactly where I was standing!
