 Originally known as the "Molly and Johnny Theme", the piece is not the main title theme of the film, but a secondary love theme for the characters played by Dee and Donahue.Following its initial film appearance, the theme has been recorded by many artists in both instrumental and vocal versions, and has also appeared in a number of subsequent films and television programs.The best-known cover version of the theme is an instrumental version by Percy Faith and his orchestra that was a Number One hit for nine weeks on the "Billboard" Hot 100 chart in 1960.
