Cleaning up songs for politically-correct ends is one thing. "Dramatising" perfectly good lyrics, thus stripping them of the irony therein, is far more risible. When Christy Moore sang Woody Guthrie's Ludlow Massacre, in the verse in which the "red-neck miners" put the state troopers to flight, Christy sang "you should have seen them bastards run" instead of Woody's "you should have seen them poor boys run". I know which version I prefer!
