First Wives Club started this thread, but it's worth repeating (that photo is priceless--whoever is on the left really looks like she's trying hard but doesn't want to be there...) I didn't see Saturday Night listed here yet.
BRAINCHILD (1974) Despite the fact that the poster says Ambassador Theater, the show closed in Philadelphia. Tovah Feldshuh had the leading role. Supposedly the set was environmental in that it started at the entrance of the theater, filling the walls of the house, and on to the stage.
DADDY GOODNESS (1979) closed in Philadelphia (I think) after opening in Washington. This show was Freda Payne's consolation prize for losing the leading lady role in DOCTOR JAZZ to Lola Falana.
Remember this one??? Randy Quaid and his wife almost hit Broadway with unbearable force! They were aiming for the Belasco. LONE STAR LOVE (2007) closed in Seattle. The show that got Mr. Quaid banned from Equity for life!
TURN TO THE RIGHT (1981). This got some of the worst reviews I've ever read. Even though Buddy Ebsen is featured in the credits twice, I don't see him listed as the top-billed star, which I'm almost certain he was. Closed in Beverly Hills, haha!
Is the COLETTE with Diana Rigg the same COLETTE that John Dankworth wrote for his wife, Cleo Laine? It played for a while in London with Cleo. I have the old LP and some of the songs are qhite good, IMO. In a long-ago interview, Cleo described how they produced it on a budget and had one person--Kenneth Nelson?--playing a number of roles.
Des McAnuff incredible visual soulful version of THE WIZ that played down at La Jolla Playhouse a few years ago. It was incredible.
Casey Nicholaw's ROBIN & THE SEVEN HOODS from Old Globe a few years ago...It was good, entertaining.. Will Chase and Eric Schnider were great and production design was fantastic...The book def needed some work but there were two amazing bringing the house down numbers
MINSKY's that played at The Ahmason a few years ago was also entertaining
Re: Harmony and Egghumor's post showing the pre-Broadway Philly production that stopped in rehearsals because of money shortages.... That was actually the second attempt and the second failure...
I recall going to a Bway Workshop for the show a few years ago, where a THIRD production team was trying to bring it Broadway... that never found a theater and fell apart, too, so Manilow's dream project has been attempted 3 times, I believe.
