At first, there's a charm about the story that New Jersey police didn't recognise Bob Dylan when they stopped him:
The police officer drove up to Dylan, who was wearing a blue jacket, and asked him his name. According to Woolley, the following exchange ensued:
"What is your name, sir?" the officer asked.
"Bob Dylan," Dylan said.
"OK, what are you doing here?" the officer asked.
"I'm on tour," the singer replied.
A second officer, also in his 20s, responded to assist the first officer. He, too, apparently was unfamiliar with Dylan, Woolley said.
The officers asked Dylan for identification. The singer of such classics as "Like a Rolling Stone" and "Blowin' in the Wind" said that he didn't have any ID with him, that he was just walking around looking at houses to pass some time before that night's show.
The cops took Dylan back to the venue, where staff vouched for him. (Although they must have been so tempted to go "nope... never seen this guy before, officer". I know I would have done.)
So, a little charming footnote. Except... all Dylan was doing was wandering round the neighbourhood. Why would that even require police intervention, much less proving who you are?
