BTW, the best online archive of live concerts can be found at Archive.org. Check it out. There are hundreds of Grateful Dead concerts, as well as, many other bands.
Update: I was checking out some of the comments from fans about this show and this one really stuck out and reflects my feelings at the time.
"There was a weird energy...and it was contemplative to say the least. This show wasn't as much of a rocker as a soul-searcher. You gotta hear it as a story instead of a party.... and during this amazing standing on the moon....Jerry closed his eyes through the entire song, never opening them from my point of view. He seemed to almost wince in pain singing this song and i know i saw an occasional tear from the corner of Jerry's eyes. He really felt this night....it was plain in his face, for all to read. He was carrying his ol' burden at this show...u could tell, and it was a deep trip. He let us out alive...but it wasn't long for him afterward. When hearing it now, i detect the warnings.....as if Jerry was saying "Yeah, you may hate this, but I know u rider....gonna miss me when i'm gone............." This show was a slice of what made the dead experience, and so often, that was not a smoking or perfect set-- It was life....full of the ups and downs that make us human. This show was equal to the 'real' Dead experience....a mountain of emotion....and not all can be pretty. Indeed, at this show, some got raw."
