They're not losing audience, they've just become more selective in choosing their fans..
That's what they said in an interview a few months ago. Doh!
And Natalie isn't fat, she's just big boned.
Interesting you mention that because just over a week ago Colin Cowherd on his radio show on ESPN Radio (The Herd with Colin Cowherd) was not thrilled that Prince was going to perform at the next Super Bowl halftime show; he openly wondered if it was possible for the Dixie Chicks to perform during the Super Bowl (either pregame or halftime show) and his producer Chadd "The Compass" Scott promptly shot down that idea, say that after the Janet Jackson debacle at a Super Bowl halftime show the NFL would NEVER invite anyone controversial to perform at the Super Bowl. Given the fact that the Dixie Chicks are intensely disliked in the South, Texas and the Midwest, I'm not surprised at Scott's comments.
