Thanks, samir, but I think I got the whole thing off the Box. It makes me happy that the radio show predates the television show, given the way visual jokery is so important to their humor. I like that even without the aid of sight gags they're hilarious. (By the way, Noel Fielding's obsession with Polos is peculiar, don't you think?)
I'm downloading one of the stage shows as I type; really looking forward to that.
