Did the Dead tape a TV show in ’76? Those are film lights, not stage lights.
Also, this photo brings up a possibility so terrifying even TotD never had any thoughts on it until this moment: what if there were three drummers?
Also also, Mickey is once again fully immersed in his persona of Sniffles, the God of Cocaine.

Shifty Mickey.

Mickey looks a bit like Sparky here.
My best guess is that it’s from this–some of the clothes are different, but Mickey still has his smuggling visor. Perhaps they filmed two days. https://www.youtube.com/watch?v=_1BV7cfllEU
Until I enlarged the picture, I thought for sure Phil was wearing a dress.
Me too!
Donna Jean goin’ for the Cosey Fanni Tutti look, gotta love that.
And Mickey is still wearing that same stealie shirt.
