I could not find any tabs for this song no matter how hard I searched.
Therefore, I just made a tab.  It is mostly correct, I believe.
Made by Wayne Watson.  Tab created on 01-06-2009.  Let me know what you think.  It makes 
feel better about myself for using up
precious time to find the notes by ear.  Enjoy.
