"I Have But One Heart" is a popular song composed by Johnny Farrow, with lyrics by Marty Symes. The song was published in 1945. The recording by Vic Damone, his first release, reached #7 on the Billboard chart.
The song was also sung by the character Johnny Fontane played by Al Martino in the film, The Godfather, during Connie's wedding, and was on the soundtrack album to the film.
The song is adapted from the traditional Italian song "O Marenariello." Sergio Franchi used this song, both alone and in a medley with Speak Softly Love from The Godfather. His recorded versions include 20 Magnificent Songs (DynaHouse, 1976), and From My Private Collection - Con Amore (Gold Records, 1976).[1] In a rare video, Sergio Franchi can be viewed singing the medley in an unidentified broadcast on YouTube.http://www.youtube.com Sergio Franchi</ref>
