Knowing the material but having not seen the original, I believe the greatest head-scratch element was that artists of this pedigree could create a show that didn't work on this level: Neil Simon, Marvin Hamlisch, David Zippel, Manny Azenberg, Gene Saks (fired and replaced by Michael Kidd), Graciela Daniele, Peters, Short, etc.
There's some decent material in the score. For a company like this, this is a great show for them to revive as opposed to the umpteenth production of, say, Little Me or Last 5 Years.
