Ah yes, Bob - I do remember now, being about as unpleasantly surprised/disappointed by the audience' behavior that night as I was by Dylan's response. Or rather, his total lack of response.

As a performer, Beethoven had that part easier at least. When a person cannot hear you, that's one thing. When he WILL not hear you - and doesn't explain why - that's quite another. So thanks for balancing the score so well here!                  

The audience goes batsh*t crazy, you can barely hear him, and he is totally mumbly-mushy-incomprehensible.

I've noticed this too, when I've watched his live performances on TV etc   It IS odd. And the part about audiences going so crazy you can't hear the music applies to many artists. That's why I rarely bother with BIG concerts anymore, regardless of who's performing.

Live and learn!
