Folk songs are evasive--the truth about life, and life is more or less a lie, but then again that's exactly the way we want it to be. We wouldn't be comfortable with it any other way. A folk song has over a thousand faces and you must meet them all if you want to play this stuff. A folk song might vary in meaning and it might not appear the same from one moment to the next. It depends on who's playing and who's listening.
