Connie Francis recorded "Where the Boys Are" as the theme song for the motion picture Where the Boys Are a 1961 MGM release filmed in 1960 in which Francis made her movie acting debut as one of four coeds on spring break in Fort Lauderdale.

According to Francis she was on location in Fort Lauderdale when the film's director Joe Pasternak advised her that he had commissioned the Oscar-winning songwriting team of Sammy Cahn and Jimmy Van Heusen to write a theme song for the movie which Francis would sing. When at Francis' insistence Pasternak agreed to consider a submission from the Sedaka-Greenfield songwriting team behind her "Stupid Cupid" hit - (Pasternak quote:) "They've got a week but it's got to be here by Wednesday: that's when we're picking the song" - Francis phoned through to Howard Greenfield in New York City and Greenfield agreed to complete a "Where the Boys Are" theme song with Sedaka although Francis recalls Greenfield initially reacting unfavorably to the assignment (Greenfield quote: "'Where the Boys Are'? What kind of stupid title is that? Who can write a song with a title like 'Where the Boys Are'?"). Sedaka and Greenfield in fact completed two "Where the Boys Are" theme songs and so as to meet Pasternak's deadline the demos of Sedaka singing both songs were given to an airline hostess of Francis' personal acquaintance who was working a Florida-bound flight on which she brought the demos to Francis.

Sedaka and Greenfield had indicated to Francis that they both much preferred one of their two bids for a "Where the Boys Are" theme song over the other and Francis herself concurred with the songwriters' judgement: (Francis quote:) "One of the versions we loved and the other we [three] all hated. Joe Pasternak came to me after [the Wednesday] meeting with the decision. 'You're right, Connie,' he said: 'This is the [right] song.' And it was the version the three of us hated."
