I will chime in regarding bad performances by Dylan. I never saw him perform "back in the day," but have paid good money to see him at small venues (under 2000 seats) twice in the last 20 years. Had hoped the first time was a fluke. It wasn't. I came away both times feeling like the poor quality of his live performance of his music was intentional. I felt insulted and devalued. I wasn't looking for a "show." I was looking for good live renditions of his music.

Still am a fan of his music - as long as it is a recording.
