Mc: frank sinatra sings the old favorite learn to croon. Frankie sings: Learn to croon if you want to win your heart's desire, Sweet melodies of love inspire romance. Just whisper you're so marvelous and then when you do, She'll answer you you're so wonderful and nestle closer to you. Learn to croon, you'll eliminate each rival soon, If you're heading for a sunny honeymoon, Learn to croon.
