Still waiting for Maurice Hines rap version of "Alice in Wonderland" called YO, ALICE!. He swore up and down that it would make Broadway.
Come to think of it, there was a musical called ALICE starring Debbie Allen in 1977 that didn't make it to Broadway, either. Obviously it was a shameless attempt to copy the success of THE WIZ. (Saw Debbie Allen in a poster of it. One of the UGLIEST logos ever!)
Let's not forget BREAKFAST AT TIFFANY'S. David Merrick closed it before it arrived on Broadway despite its huge advance.
There was also the failed Bea Arthur tuner A MOTHER'S KISSES, and Angela Landsbury's flop PRETTYBELLE as well. Neither made it to Broadway.
Praying Decca Broadway will put "Don't Bother Me, I Can't Cope" on CD!
