I snagged a copy of your documentary on eBay just now for $8 (They say it's new and unopened, too!) I will be interested to learn more about the this person in the Ukraine of whom you speak who ostensively "came to Jesus" after listening to "Jesus Christ Superstar."
I have had a low opinion of Webber and Rice's work since it was released in 1970, as I find it blasphemous, particularly as it ends with Jesus Christ simply dead on a cross -- as only Satan himself would have liked the story to end.
By contrast, another work which came out simultaneously with JCSS was Ray Ruff's, "Truth of Truths," which set to music significant Bible accounts from the beginning in Genesis through Christ's death, burial and most importantly - resurrection, and to end of Revelation.
Like JCSS it too was a 2 LP set, and opened its first performance at the Hollywood Bowl in 1971 (Jim Backus played the voice of God!) At any rate Ruff was true to the Scripture in ways Webber and Rice did not care to be, and Ruff got the more accurate message across although the music and the performances were somewhat less polished than were JCSS's.
I'll be interested to see what your movie's take is on the topic - again where back in 1970, much music of the time reflected and inspired the Communist driven anti-war protests that in part led to the US pull out from VietNam, which in turn gave the Communists there a victory in South East Asia.
FReegards!
I’ll look for that one.
