Dylan spits out the lyrics almost hissing them at one point. If we believe this to be true then the simplicity of the phrase must not be over exagerrated. Dylan may want us to simply 'leave him alone' and only interpret his music. In the past he had proved himself to be a more than adequete historian and interpreter of blues and folk, an incredibly lyrical and imaginative songwriter, an active participant and spokesperson for the civil rights movement and a more than competent guitar and harmonica player. I'm not interested in myself as a performer.
Performers are people who perform for other people.
Unlike actors, I know what I'm saying. It's very simple in my mind. It doesn't matter what kind of audience reaction this whole thing gets. What happens on the stage is straight. It doesn't expect any rewards or fines from any kind of outside agitators.
