Oy...again with my two cents:
People who liked the movie are the main audience for the show. Right? Right.
They come to the show, and they don't see an accurate representation of the film, which is what they REALLY came to see. Right? Right.
No offense to Menken and the Steinkellners, but it's time to boot their asses off the show and go back to the film (and Marc Shaiman's absolutely wonderful arrangements of Motown). Maybe some book revisions in tune with Paul Rudnick's original screen draft so the audience doesn't feel cheated out of a LITTLE something different, but that's about it.
And if they really want to sell tickets, bring in Whoopi six weeks a month as Deloris. It'll sure as hell sell tickets.
