I suspect that the original post is an effort to flush out us old guys on this board.
I saw the original production of Godspell. It was done quite simply on a mostly bare stage with a chain link fence on three sides. I just remember the show as both entertaining and touching. Although it played off-broadway, the show toured in full sized theatres around the country to good audience response. The first Act ended with the "Let's have some wine" line, and the audience was invited on to the stage where wine was poured out of gallon jugs into small paper cups. As to why it is cut, I don't know. It may have become a question of an insurance issue... inviting the audience onto the stage. Who knows.
That was quite a few years ago, but if you have a specific question I will be happy to try and answer it.
