According to Playbill and Equity notices, It Shoulda Been You will be on/about March 26, 2015 for an open ended run. I'm not too familiar with the show beyond knowing it had a try out in 2011 and it's been David Hyde Pierce's pet project for a few years.
Did anyone see the show during the try out and have thoughts on it? Any thoughts of where it may be headed, theater-wise?
