Paul,
You probably remember the guy who played guitar, harmonica, and drum then. He played at Mallory Square each night. That dude would play Robert Johnson songs all night.
There was also a bum I met that knew all the verses to "Alice's Restaurant".
Crazy.
I was there in 1990 too for a week with friends. We only spent two days in Key West...I remember some punk smashed me in the cheek on the street for some reason..........that wasn't you was it?
