Two weeks before the Iraq invasion, the Dixie Chicks' lead singer Natalie Maines told a London audience, "We're ashamed the President of the United States is from Texas."

Their big hit, "Not Ready to Make Nice," is an unapologetic response to Maines' comment about President Bush. We hear more about the politics of pop music from Geoff Boucher of the Los Angeles Times.
