Peter has a very strange comment in the interview section in which he says he played Frankenstein 7 times - "two haven't come out yet". Given that Frankenstein and the Monster from Hell was awaiting release, what was the other one to which he was referring ? I had wondered if he meant One More Time but I checked the BBFC site and it was classified as June 1970. I've seen some references to a Hammer Frankenstein LP project although it has never been confirmed that this was ever actually recorded. I wonder if Peter's comment here is a clue to his role at least having been recorded.
Maybe he just made a mistake.
