I got a question for you: Passage: "It's Now or Never" is a ballad recorded by Elvis Presley in 1960. It is one of two popular songs based on the Italian song ``' O Sole mio" (music by Eduardo di Capua), the other being "There's No Tomorrow", recorded by U.S. singer Tony Martin in 1949, which inspired Presley's version. The lyrics were written by Aaron Schroeder and Wally Gold. The single is the second best-selling single by Presley, and one of the best-selling singles of all time.\n\nQuestion: Based on this passage, who sings the song it's now or never?
