Just found this site.

Zimmerman was a sleaze ball. I don't know anyone in The Village that "liked" him, although some of his stuff wasn't bad (if other people sang it). The way he used Joni was cruel. Dick Farina hated his guts, and said so in song. I shared a room with Phil for a while in SoHo, so I know Phil's opinion of Zimmerman.

Illustrative story: One night in the Gas Light Zimmerman had been drinking beer and peeing his jeans. He smelled terrible. But when he started to rub his pee-soaked jeans on my leg playing "doggie" I had to cold cock him. Jack Lass, the manager, carried him out into the street until he woke up. That was the "Dylan" of The Village.

A close listen to "Positively 4th St." will confirm what I'm saying.
