In the early 1980s The National Theatre production of The Mysteries was filmed and broadcast in three parts on the then new Channel 4 television (in the UK). Music was by the Home Service and there was a wonderful turn as God by the late Brian Glover. At the time I recorded (most of) them on a fairly primitive VHS machine.   The tapes, now 20-odd years old are pretty worn out and I have been looking for a replacement but they do not appear to be available on DVD (or VHS).   

Can anyone help?

Cheers
