I could definitely see doing something like that (the shout) that had I been an obsessive Dylan fan at the time of that concert. I sure wasn't.

Course I'm even more conservative than the "Judas" man when it comes to Dylan.

I think his very first album, with "Talking New York Blues", etc. was delightful--with its understated musical arrangments--it helps if you're solo--, its homage to Woody, and its sly humor (also Woodyesque).

From then on Dylan became progressively more full of himself and more turgid.   Perhaps they go together. But it's not a requirement for memorable music or to address social issues--see John Prine,

And please spare me the drivel about how we owe the Band to the new Dylan.    The Band likely could have made it without Dylan.   The Band kept their sense of humor. Dylan appears to have lost his.

Added to which, if the clip has any fidelity, the sound of the second half of the concert was dismal.
