There'll be a rainbow around the moon. You'll fall apart when you hear that tune. Every day will end too soon. When you fall in love. You'll get weak in the knees when you see her smile. You try your best to hid it cause its not your style. You let it get you cryin like a little child. When you fall in love. Chorus:. When you fall in love. Its out of your hands. It gets into your heart. It changes your plans. But youll only understand. When you fall in love. The summer breeze will chill you to the bone. You'll walk the floor til the break of dawn. Sometimes youll feel so alone. When you fall in love. And you wont notice but the day that it shows. That lightll follow you wherever you go. And thats how youll know. When you fall in love. Chorus 4x
