Ironically...

Totally unrelated to this live stage production, but I have been trying to remember the name of this show, on-and-off, for the past several years, lol. So thanks to whoever wrote this article.  :')

Going back to this stage show, though, I'm curious how the details of this would've worked..... They probably did what Disney does with a lot of their mascot stage shows: have the mascots perform to pre-recorded audio of the music and the characters speaking. If that were the case, there is a chance of finding that original audio somewhere in its raw form (like on a cd or something). The alternative to this would be microphones set up within the mascots to allow the performers to deliver the required dialogue, but the chances of that are slim, given how expensive it'd be to have microphones for each performer, and the challenge of finding performers that can imitate the characters' voices (while performing in heavy mascot suits)...

Final thoughts: if there were a way to find out what stops were made on that revival tour, there might be a way to track down another venue that could still have the audio. Though, if there was only one set of the audio component that travelled with the performers themselves, this would be a non-starter.

Interesting media... I hope we find more of it in the near future...
