Here is the official site of David Hyde Pierce's directorial Broadway debut of the musical "Shoudla Been You" that he wrote with his husband, Brian Hargrove. I'll add pictures and so forth when I find them. I saw this musical when it came to a theatre near my house back in 2012 and although I can't say it was my favorite, I loved the music in it and this production (the NYC one) is being directed by David Hyde Pierce (Niles Crane of course) but also has Harriet Harris (Bebe Glaser), and Edward Hibbert (Gil Chesterton) in the cast. I'd love to see this version but I really hope they have a soundtrack!
