<> just you know why - why you and i will by and by - know true love ways sometimes we'll sigh - sometimes we'll cry and we'll know why just you and i know true love ways throughout the days our true love ways will bring us joys to share with those who really care sometimes we'll sigh - sometimes we'll cry and we'll know why just you and i know true love ways
