I found this at the end of a VHS tape I’d recorded for school in 1984. It’s an entire commercial break, a continuity announcement plus the start of Channel 4 News on a day when an important international news event had taken place. More interesting than the preceding programme which I’d recorded on purpose.

I think I have three more like this. I was recording the 24 part series The Living Body onto 180 minute VHS cassettes, letting the timer run over by about 5 minutes. Each of the four tapes should have something similar at the end, about six weeks apart.
