There is now what appears to be a complete version of it on YouTube.

It is gratifying to know that so many people remember these wonderful productions. I saw a 30 minute section of 'The Passion' on Easter Day 1977 on the terrace overlooking the Thames featuring Mark McManus as Jesus and Derek Newark and Trevor Ray (and maybe James Grant and Dave Hill, if I remember well) as the soldiers. It was my very first experience of theatre and was so magical.

Peter Hall let Bill Bryden's Cosstesloe Company die as a tactic to fight the Thatcher government's Arts polices. A terribly short-sighted decision. So many wonderful actors were involved in The Mysteries Derek Newark, Brian Glover, Jack Shepherd, Edna Dore, Brenda Blethyn, Robert Stephens, Don Warrington... I could go on and on. It was a true landmark of British theatre and those recordings should be released so that a new generation can experience a taste of how wonderful they were.

By the way, thank you Chris B, for your opinion of the "greatest performance of the cycle" being Derek Newark as Abraham. He was my Dad and was proud of that performance. It's nice to know that it is remembered.
