I'm Sorry I Haven't a Clue introductions at the Richmond Theatre

In early November I attended a recording of Radio Four's ;antidote to panel games" at the Richmond Theatre in... erm, Richmond. I've included the long time producer of the show, John Nay-Smith saying a few words of introduction and welcoming the panel, but have stopped short of revealing the content of the shows recorded, the first of which was broadcast on the 17th November, and will be repeated on Sunday lunchtime.
