It's now or never... The Answer!

Many thanks to all of you who took a guess at last week's question, "The melody from what aria matches the chorus to Elvis Presley's 'It's Now or Never'?" 72% of those who guessed, guessed correctly. It is based on Eduardo di Capua's "O Sole Mio". Many of you know "O Sole Mio", as it is one of Pavarotti's famous aria's.
