A long time ago people on TV didn’t know what a rave was. Here Inspector Morse and Lewis find themselves at one. ‘It’s like some sort of an orgy!’ says Morse. Lewis wears a tartan cap to blend in. It makes him look proper Geordie.

I have a vague memory of speaking to someone who was an extra in this scene. They had an actual rave for a few hours and filmed it. And they got paid! Nice work.
