How many songwriters have you heard tell the story about the person who goes upt to them and, thinking it to be cute, proceeds to explain the meaning of the song to the songwriter? And the songwriter doesn't recognise that particular subtext!!!

It's not just singers who re-interpret. BUT if it has touched someone why should the writer quibble? That was their intention. Too bad it was not quite how it was intended - hey that is what we call LIFE.
