For the sake of nerdy interest, this is actually from Philips N1500 rather than Betamax, and it's more about programme material than continuity. It includes the majority of the very last Vision On, from 11th May 1976 (the first few minutes are missing).

Towards the end of this edition there is a sequence of the cast dressed as insects miming to I Want To Hold Your Hand by the Beatles. I've had to remove the music from this as it was causing the video to be blocked worldwide.

The final 15 minutes is an Open University forum from 1978 chaired by Magnus Magnusson seemingly from a school hall, discussing social deprivation with specific reference to the problems of the Lilybank estate in Glasgow which had been the subject of a highly controversial documentary The Fourth World earlier in the year.

I've featured highlights of this material in previous uploads, but this presents everything unedited, exactly as it came off the tapes.

As usual, if you watch the 720p50 stream, the picture should retain its original "interlaced video" look.
