Why is my heart so light? Why are the stars so bright? Why is the sky so blue Since the hour I met you? Flowers are smi - ling bright Smiling for our delight Smiling so ten - der - ly For the world, you and me BRIDGE I know why the world is smiling, smiling so ten - der - ly It hears the same old story through all e - ter - ni - ty MELODY Love, this is my song Here is a song, a ser - e - nade to you The world can - not be wrong If in this world there is you I care not what the world may say; With - out your love there is no day. So, Love, this is my song, Here is a song, a ser - e - nade to you.
