Z526: I did just ascend my loft, at Mrs Aerohack's behest (annual retrieval of Christmas decorations). Stumbled over a box of old videos, and among those that fell out was 'Man in the Sky' devoted to the young David Perrin. Had forgotten it was there, can't remember anything about it, but when I've refreshed my memory with a viewing or two I'd be happy to loan it to any posters on this thread who might be interested.
