Success is inevitable for a musical in which Fred Astaire appears - if it was also written by one of the most talented composers of his time. Irving Berlin, Jerome Kern, George Gershwin - all these brilliant composers knew how to deal with the fact that not only Astaire's legs are like an instrument, but that his whole being is filled with music.
