I was there it was a week-end festival held at a Holiday Camp at Caister,Norfolk, England
and the various bands mingled with the fans for the whole week-end.
I remember playing Pinball with Lemmy of Motorhead and he was very good.
Motorhead were so loud in the small hall that we were forced to leave the hall before our hearing was damaged.
Other bands playing were Spider,Twelfth Night,Dumpys Rusty Nuts,Killer,Hawkwind and Motorhead.
