For there were many things I didn't know And Daddy always smiled, took me by the hand Saying, "Someday you'll understand" Well, I'm here to tell you now, each and every mother's son You'd better learn it fast, you'd better learn it young 'Cause someday never comes Some Day Never Comes by CCR I don't Understand Some day I will exercise more Some day I will eat less Some day I will listen to more music Some day I will practice playing music Some day I will watch less television Some day I will get back to riding bicycle Some day I will understand But some day never comes
