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 analyzin' 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
