The song title was announced on the BBC's Eurovision Web site.
"The more you listen to it, the stronger it gets," the BBC quoted the entertainer as saying about the song. "It's not a one-time listen."
Humperdinck, 75, is best known for his 1967 hit "Release Me." He has sold more than 150 million records and was announced last month as Britain's contender for the Eurovision Song Contest, which is to take place May 26 in Azerbaijan.
