Thanks for ibdb.com. I've used it before but I was never clear where the info was coming from. If they are taking info from the show's registration, that's helpful to know.
I checked Ohio State Murders on ibdb.com, and that is listed as "Play" and "Original." So I guess the producers registered it as a new play? Or was this just how ibdb decided to categorize it (since it's the first entry for that piece)? It sounds like you're saying that "Original" tag is a reflection of the show's registration?
In any case, the Administration Committee deemed it a Revival. Which makes sense to me. It feels more "historical/popular repertoire." It was first done in 1991, even though it wasn't done in NY until 2007. And that was a much different production than this one.
