If my memory serves me well, this is the show where Bob's guitar strap (or the peg it hooks onto) broke during Around and Around. They crew tried to fix it mid-song, Bob got that deer in the headlights look, and Jerry just blazed away. Finally, Bob gave up on the guitar and took the microphone out of the stand. I think he even tried a few Roger Daltrey-style swings. . . or maybe it's just a trick of my Who/Dead fixation . . . see my note for the 12/11/72 Winterland show.
