Qui (http://"http://en.wikipedia.org/wiki/I_Have_But_One_Heart") su wikipedia.org dicono che:
"I Have But One Heart" The music was written by Johnny Farrow, the lyrics by Marty Symes. The song was published in 1945,the song is adapted from the traditional Italian song "O Marenariello."
Non sarebbe meglio dire che "I Have But One Heart" è una cover di "'O Marenariello",anche perchè Vic Damone (prima versione Inglese) canta in napoletano nel mezzo del pezzo le frasi originali di"'O Marenariello"
