Whenever this issue comes up, I think of the first line: "Tho my sails be torn and tattered and my mast be turned about." Is there anyone who knows boats that this line does not grate upon? Some things call out for improvement, some should be left alone. When someone tells me that they wishto sing my song but they want to personalize it for their own use, I am thrilled that they like my song. Perhaps I need another decade or two to become jaded and crusty in my attitude. I am not writing the bible. If I were perfect, I would be upset when someone pays me the compliment but feels it needs a little tweak. I'm not either. When I have a Senior Moment" in the middle of a song, often I just throw a word into the breach in order to keep going. Anyone who has looked in Child knows that there is no one definitive version of most of the traditional ballads. Which one is right? Sometimes it is even possible to 'reconstruct' a more complete [and therefore more perfect?] version from the existing fragments. What is right?
