His Butler's Sister on AllMovie

In this frothy musical comedy, Ann Carter (Deanna Durbin) is an aspiring singer from the Midwest who decides to move to New York in hopes of advancing her career. Her half brother, Martin Murphy (Pat O'Brien), is already living in the Big Apple, and has told her that he's doing well as a businessman; however, when she arrives at his door, she discovers that he's actually working as a valet for Charles Gerard (Franchot Tone), a well-known composer. This is good news for Ann, since Charles could doubtlessly do a great deal to give her career a boost, but Martin is hesitant to talk to his boss about Ann. Charles is inundated with pleas from semi-talented would-be musicians all day long, and putting another in his path would earn Martin no favors. However, Martin soon has bigger worries; it seems that Charles has developed an interest in Ann which Martin is convinced has nothing to do with music. As you might expect, Durbin sings several songs, including "In the Spirit of the Moment," "When You're Away," and an aria from Puccini.
