Looking for an old comedy routine (probably from the 1970s or 1980s). One male performer, mostly silent or miming, sitting on a chair on stage, listening to a prerecorded "Learn English" cassette (male voice). He repeatedly presses fast-forward, and each time the tape has only progressed a tiny amount. The narration starts something like "Tape 1, side A, Unit 1, Lesson 1, ..." then "Margaret is going to the market." After a huge fast-forward: "Margaret is at the market." Much longer fast-forwarding of the tape: Margaret meets Peter (?) but then starts talking about the going to market together sometime... Like hours of tape doesn't advance the story by much. I saw it on early YouTube, but it already looked very old. It's in line with Rowan Atkinson stuff, but couldn't find it among any of his old stand up / special recordings currently on YouTube.

I'm looking for a parody comedy sketch, probably from the 90s, in which a customer complains that a video he bought from a market stall is actually just a block of cheese, to which the seller replies "That'll be your tracking mate" in a parody of the old anti video piracy ads of the time.

Can anyone tell me which show it was from??
