Two releases of the score of the film, composed by Nino Rota, have been released.
"Love Theme from Romeo and Juliet"
The film's love theme was widely disseminated, notably in "Our Tune", a segment of BBC disc jockey Simon Bates's radio show. In addition, various versions of the theme have been recorded and released, including a highly successful one by Henry Mancini, whose instrumental rendition was a Number One success in the United States during June 1969.
There are two different sets of English lyrics to the song.
- The film's version is called "What Is a Youth?", featuring lyrics by Eugene Walter, and sung by Glen Weston. This version has been released on the complete score/soundtrack release.
- An alternate version, called "A Time for Us", featuring lyrics by Larry Kusik and Eddie Snyder. This version has been recorded by Johnny Mathis and Andy Williams, among others. Josh Groban performed "Un Giorno Per Noi", an Italian version of "A Time for Us".
- A third version is called "Ai Giochi Addio", featuring lyrics by Elsa Morante, and has been performed by opera singers such as Luciano Pavarotti and Natasha Marsh.
