From 2/18/71, when Mickey left the band, to 10/19/71, when Keith made his debut, there were not enough Grateful Deads. I mean, really: this is absurd. We need at least two or three more musician, not to mention the fact that this is nowhere near the proper amount of amps. We have here a normal, human amount of amps; that’s not the Dead’s way of doing things. There are also no random naked children wandering around the stage.
It’s just a mess.

There’s also a Dave’s Pick with 5 Grateful Deads because Mrs Donna Jean Godchaux was giving birth but her husband couldn’t be arsed to take a day off work to be there.
Based on my limited research: 5 Grateful Deads is a Just Exactly Perfect number of Grateful Deads.
True: December of ’73 was the Third Great Quintet.
This is like Anti-Precarious Lee was there. Stable stacks, custom speaker supports, and ropes holding back the crowd and everything. So orderly.
I can’t enlarge this enough to be sure, but is that Marmaduke behind Billy with maracas or something?
The great Jesse Jarnow came to that conclusion, as well.
21 Amps by my count. Isn’t that Bear between Jerry and Bobby?
I believe there were only 5 Grateful Deads from Keith’s first show, 10/19/71 until Pig’s return, 12/1/71. Donna Jean didn’t join them until 12/31/71, Pig was out and so was Mickey. So, there was a third great quintet in Oct and Nov 1971.
