Oh wow....I need to get into my time machine to go way, way back. Back in the late 70's and early 80's there was a man who produced catfight movies. His name was John Cain, if I remember correctly. I believe he might have been located in the Boston area, but I'm not sure. Anyway, I bought one or two of his films. I believe he used 8 or 16 mm film to record the fights. I must have bought VHS tapes of them, because I didn't have a projector to watch them. I can't remember any details, girls names, or the titles of the films. If any other old timers out there read this, they may have known about Mr. Cain.
I also bought several VHS tapes from Crystal when they were known as Crystal Films, before they switched to Crystal Video. They had a video series called Catspats before they started their video magazines. And they also published a magazine, Catspats, that had some excellent pics of catfights, including quite a few from Frank Rusha.
That's about as good as my memory allows.
