I have to admit that I did not much like this when I saw it 40 years ago. I cannot imagine it succeeding today. First of all, Ann-Margaret may have toured it, but the role of Mona is pretty small; I can;t see why a real star with alternative work options would want to tie herself up to appear in this. Secondly, the real sar of the show was Tommy Tune's staging; unless they simply copy it, they are never going to improve upon it. 40 Years ago, there were people who thought it was raunchy and that that helped the box-office. Today it is quaint.
To the person who referred to Mame and Funny Girl; Funny Girl was always a flawed show that could succeed with a great star turn because there were enough high-spots to offset the low ones, e.g., book scenes, Rat-tat-tat-tat,listening to Nicky Arnstein sturm-un-drung, etc.
I continue to believe that Mame could succeed with a great star performance. It is a fun, old-fashioned musical comedy with several great roles, opportunities for show-stopping numbers, lots of brass in the orchestra, a number of well-loved songs, Bsst Little Whorehouse has the title.
