This is Broadway at its best, with a hysterical tap-dancing spoof of 1930's Busby Berkley-style movie-musical spectaculars. The show tells the story of Ruby, just off the bus from Utah, who in the span of one day falls in love, gets cast as a dancer in a Broadway musical, saves the show by moving it to a Navy ship, takes over for the star, becomes a hit sensation, and gets married, to boot!
