Well in NYC you had the 2007 revival that Marcia Milgrom Dodge directed for TheaterWorks USA at the Lortel (and subsequently toured on and off for the following ten years or so).
I heard about a production that was right before COVID that got good reviews. When the dust speck gets lost in the clover field, they dropped a million plastic ball pit balls from the ceiling, a la the toys in Mike Birbiglia's The New One. Does anyone have any more info on that show?
Ditto the TheatreWorks USA version. I've worn out that recording and I like it even more than the original Broadway cast. Flaherty and Ahrens are on record saying that's the "complete" version of the show.
The TYA version, yes. MTI also licenses the two act version that reflects the changes made for the 2002 tour with Cathy Rigby. They also have the "Junior" version, which I think is the TYA script with some keys adjusted for young performers, as well as a "Kids" version, which they list as a 30 minute version.
The Cathy Rigby was strange. The production was too long, and oddly sexy, for kids. The kids in the audience seemed bored and Rigby would snap at them for not answering her fourth wall breaking questions.
"Who wants to bid on Horton the Elephant? (no response.) Look kids. The lights are up. We've established this is the audience participation part of the evening. I won't let the show go on till you answer. So who. wants. to. bid. on. HORTON THE ELEPHANT?!" (Tiny terrified hands raise in the air.)
