I saw MADAM at Goodspeed last year and it is very dated. It is a genre that does not exist on Broadway any more: the topical, politically satirical musical, written quickly and designed to run a season or two at most. Shows these days are written to run for years and years and therefore eliminate any references to current events that will quickly grow stale. I'm pushing 50 and many of the political references in CALL ME MADAM were way over my head. It's way more topical than the movie.
Remember that even it its day, with Ethel Merman at the peak of her popularity, MADAM only ran about 600 performances, half that of ANNIE GET YOUR GUN, and far less than other shows that opened around that time, THE KING & I, and GUYS AND DOLLS. Sure, the songs are great, but the show is almost unrevivable except in places like Goodspeed, Bay Street, or Paper Mill where it would be guaranteed a certain amount of patrons due to the subscription base and would be seen having value as an historic piece, if nothing else.
