During the Second World War when this film was made on the MGM lot in 1944, other than harpists there were very few women in major world symphony orchestras. In order to justify the cast of women instrumentalists who are June Alyson's roommates in the story, the on-screen orchestra has an unusual proportion of females, among them the dumb blonde Marie Windsor ("My Friend Irma") on classical clarinet! Even today when there are numerous women in all major orchestras, it is still unusual to see as many women in the brass section as those who are pictured in this film.
The director of the orchestra, Jose Iturbi, best known today as an MGM personality, was actually the conductor of the Rochester Philharmonic Orchestra from 1936 to 1944.
The member of the band at the Army base who breaks up Jimmy Durante's performance of "Umbriago" by singing in front of the microphone is Eddie Jackson (ne Edward Jacobs), Durante's long time partner in the night-club team of Clayton, Jackson and Durante. The trio performed for years on vaudeville and at New York's Club Durant (sic) but it was the bottom-billed Jimmy who became the star. Lou Clayton, who gave up show business to manage his partner's career, made Jimmy a millionaire.
