In the show's defense, no one put that much detail into fact checking sitcoms back then. Seriously, did they honestly think a bunch of us would be on a world wide computer network 33 years after the show's very lame ending discussing minutiae like this?
So, the episode that mentions Bob Dylan is 1967, at least 3-4 years after there would have been any possibility that he would show up at a protest rally.
