I hear singing and there's no one there I smell blossoms and the trees are bare All day long I seem to walk on air I wonder why, I wonder why ? I keep tossing in my sleep at night And what's more I've lost my appetite Stars that used to twinkle in the skies Are twinkling in my eyes I wonder why ? You don't need an*lyzin' It is not so surpisin' That you feel very strange but nice! Your heart goes pitter patter I know just what's the matter Because I've been there once or twice! Put your head on my shoulder You need someone who's older A rub-down with a velvet glove! There is nothing you can take To relieve that pleasant ache You're not sick, you're just in love! Repeat verse and chorus simultaneously Now you know why! Now I know why! I'm just in love! ~ from the 1950 Broadway musical "Call Me Madam" Words and Music by Irving Berlin. 1950
