It will NEVER be revived on Broadway unless they re-write the book and most of the score. I saw it on Broadway with Julie Andrews and remember liking her, Robert Preston -- oh, wait, that's the movie -- the sets, the Jazz Hot number, and that's about it. I saw it last summer in Ogunquit and thought it was better in a more intimate setting, but still felt it was thoroughly mediocre, and best suited to summer theatre. In the closer setting, I particularly hated the way the Norma role was written (and performed), and I started to wonder whether it was written a little less over the top in the movie or, as appreciated as it was, if Lesley Anne Warren's performance was under appreciated at the time, since she was a hoot in the movie.
If Julie Andrews hadn't been i the show originally, it never would have even been attempted for Broadway.
