As for the new ending for Pippin...
I think I've recounted this here before... Well, at least on the "old" board... In any case...
From what I understand, a director in London tried this out a few years ago, and Mr. Schwartz liked it. I believe it was incorporated into the Papermill Playhouse production a few years ago, but I'm not sure. However, I did hear about this "option" directly from Mr. Schwartz's assistant, so...
Basically, the whole cast is treated like one big ensemble, a troupe of actors. As the Leading Player "directs" the show, he starts picking out various people of the ensemble to play their parts - Charlemagne, Fastrada, Louis, Catherine, etc. At the "end" of the show, the "Magic To Do" vamp starts back up again. Pippin, Catherine and the Boy (which was played by an adult too), take their places back in line. Then the Leading Player starts looking through the line for another candidate... He picks a new "Pippin"... and the cycle starts all over again...
Fade to black...
Or something like that.
I had a very detailed e-mail sent to me about the London ending, but that was two laptops ago, so...
