I haven't met a musical that I couldn't find something to like about it, so although the story is somewhat bland one can still enjoy the good highlights. It's wonderful to see these stars in their prime -- Bing, Mitzi, Donald, Jeanmaire, and Phil Harris as the father figure.
The dance routines of "You're the Top" and "It's Delightful" are great musical show stoppers. Basically Bing and Donald play the part of two showmen who unknowingly sign two different dancers, Mitzi and Jean, to be the star in their musical. Obviously they have some sorting out to do on this matter while all are sailing back to America.
In my later years I'm learning to appreciate Bing's movies more than when I was young. All in all this is pleasant entertainment that leaves you with a good feeling.
