Madonna played Coachella last night, going on 20 minutes late and performing a short but stadiumlike set. She entered via a giant disco ball that split in two, then sang six songs, beginning with “Hung Up” and ending with “Everybody.” In a political nod that seemed somewhat juvenile, she changed the lyrics of “I Love New York” to “Just go to Texas and you can such George Bush’s dick.” Which, of course, you really can’t do and wouldn’t want to do, even if it meant changing the world for the better.
