I did have some footage of Mark Hamill presenting a European Lottery programme dressed in his flight suit, from about 1980. Unfortunately the VHS degraded and eventually became unwatchable.
The guy who copied it for me (in the UK) back in the early 90's used to print a small A2 sized fanzine about Sci Fi. He was also a big proponent of copying Laserdisc special editions (Terminator 2 and Aliens etc) to VHS for people.
I wonder if he is still out there?!
