Gene Kelly, Betty Garrett & Ann Miller

On the Town is a 1949 American Technicolor musical film with music by Leonard Bernstein and Roger Edens and book and lyrics by Betty Comden and Adolph Green. It is an adaptation of the Broadway stage musical of the same name produced in 1944 (which itself is an adaptation of the Jerome Robbins ballet entitled Fancy Free which was also produced in 1944), although many changes in script and score were made from the original stage version; for instance, most of Bernstein's score was dropped in favor of new songs by Edens, who disliked the majority of Bernstein's music for being too complex and too operatic for film audiences. This caused Bernstein to boycott the film. (Wiki)
