"It's Now Or Never" based on the Italian song of the Neapolitan language, "O Sole Mio". In the late 1950s, while stationed in Germany with the U.S.Army, Presley heard this song. It's also likely that he was inspired to record this because of his fondness for Mario Lanza who had first popularized "Oh Sole Mio" to American audiences and who had died the year before "It's Now Or Never" was recorded. Released on July 5, 1960, "It's Now Or Never" became Elvis' biggest hit, it was a number one smash in almost all countries around the world. And it was also the largest global success of the year 1960 with a total of 10.981.000 points.
