You have Cluedo? Excellent! A couple of years ago I started buying up old tapes and DVDs of the show from Ebay, but I don't have a VHS player any more and my series 2 DVD has stopped working, so the only working series I have at the moment is the first. Richard Wilson was certainly the best Rev. Jonathan Green, but contrary to many opinions I also really liked Kristoffer Tabori as Prof. Peter Plum in the first series - he was young, American and rich, so not the typical mad professor character, but he was hilarious in the studio, loudly remonstrating every time anyone suggested he had anything to do with the murder (especially during the episode when he did!). He went on to play the assassin droid in the Knights of the Old Republic computer games, another star performance.
