Nothing to do with his influence on the Beatles but just a random thought on Bob.
I was listening to Highway 61 last night and Queen Jane Approximately came on (which is purportedly about Joan Baez). It got me thinking what a jerk he could be back in those days. He has a lot of nerve to write a song like that about her, putting her down. After all, he was the one who treated her like crap, cheated on her, and broke her heart. Just goes to show that you can be the total a**hole in a relationship, but if you write a good enough song about it, people will take your side.
I still love him though, of course. He was arrogant as hell in the '60s but he was only in his early twenties. I don't know too much about his relationship with Sara but I hope he's learned to treat women a little better.
