To clarify, the original synopsis provided by the production did say, "...performed by a rotating cast of some of the funniest people on the planet." (emphasis mine)
Not sure when they changed the "performed by" to "read by." According to what's available on the wayback machine, the language was updated on the 'All In' website sometime between September 24 and October 1. (Tickets went on sale on September 30.) Even after the synopsis was changed to accurately reflect that this is a reading, the subheader on the site continued to promote, "All In is performed by..."
I hope the "performers" and the production impresses within the context of a reading, but you can't blame ticket buyers for feeling mislead, especially at these prices. What a marketing misfire. If I was in the cast, I'd be pissed that the pre-show promo did not appropriately set expectations. I suspect they'll be facing a lot of disappointed and disinterested audiences.
