Fly me to the moon    Let me play among the starsLet me see what spring is like On Jupiter and Mars
In other words, hold my hand
In other words, baby, kiss me   
Fill my heart with songAnd let me sing forevermore  
You are all I long for
All I worship and adore
In other words, please be true
In other words, I love you
