Come Blow Your Horn is the film version of Neil Simon's first successful Broadway musical. Alan (Frank Sinatra) is a swinging single playboy who lives in a New York City apartment. Buddy (Tony Bill) is Alan's impressionable younger brother who wants to be independent and move from the confines of his parent's home. He moves in with Alan and begins to get an education from Alan about the world of swinging bachelors. When Buddy is such an alert student that he begins stealing Alan's girlfriends, Alan regrets ever letting his little brother move in with him. Alan soon realizes that he's been a bad influence on his little brother and begins to change his ways. He starts to encourage Buddy against being a playboy and picks a gal of his own to settle down with. Norman Lear wrote the screenplay and Bud Yorkin directs this fun musical comedy from the year 1963.
