There was more credibility to the rumour of a new production of Kiss of the Spiderwoman. That may come in 24/25. It takes time to put the finances together for big shows, and gets more difficult every time an expensive show flops. This past year saw at least four expensive flops in Bad Cinderella, NYNY, & Here Lies Love, and Once Upon a One More Time."
I can absolutely confirm that Kiss of the Spiderwoman was gearing up for spring on Broadway. They did an extensive workshop at New 42 with Ariana DeBose, Javier Munoz, and Robin de Jesus. However, they wanted it to be the big stary revival event of the spring (it will have a hefty capitalization and running cost). And producers realized that they would have major competition from the extended Merrily and soon-to-bow Cabaret. DeBose will theoretically also have an even bigger box office draw if they wait, with films like Kraven, and Argylle releasing ahead of her return to Broadway. They believe next season will position them better and be a less crowded marketplace.
Anyway, back to your previously scheduled Mame convo! (Which, I agree with other posters, will not return at this point without a Midler-level star).
