Well, per the revised script licensed for amateur and regional productions, it is based on the changes made for the Original London production.
Crisparkle, Helena, and Neville's confessions had been changed to include a reprise of "A British Subject", which in my opinion, is a welcome change, because it can be quite monotonous to have most of the suspects singing the same reprise of "No Good Can Come From Bad".
Durdles was given a confession during the rewrites.
Rosa, Bazzard, and Puffer's confessions are pretty much what you have heard on the OBC recording with all the multiple endings.
"The Name of Love/Moonfall" has been moved to Act II, where as in the OBC, it was the Act I finale. (I prefer the latter.)
"A British Subject" replaced "Ceylon".
That's all of the changes that I can think of, off the top of my head.
Thanks for the info!
Cheers,
