Lincoln Centre Library for the performaing arts has an exhibit of set designs and costumes from various Public Theatre productions over the years and they're showing clips from Public Theatre funded shows, and we stumbled into it just as they were showing the opening number from Caroline or Change. This was followed by scenes from the original Chorus Line. It was worth the trip we took to return some videos.
Sounds really interesting!
I did some online searching and here's a link to more information on this exhibit from the library's website:
