I went to a Fringe event a few years ago which was Phil Jupitus in conversation with Brian Cant, talking about Trumpton, Chigley and Camberwick Green, showing clips, and it finished with a whole episode chosen at random. When the opening credits of "this is a box, a musical box..." started, the whole audience did a sort of "ohhhhhhhhhhh" and I'm absolutely certain I wasn't the only one a bit damp around the eyes.
We watched an episode of Camberwick Green in which PC McGarry questioned Windy Miller about boys fishing without a permit, but Windy refused to grass them up, then he drank a lot of strong cider and fell asleep. Meanwhile, PC McGarry went off to question Mr Crockett the garage man, refuelled his police motorbike and then went off without paying. It's quite subversive really.
