Check the just ending Dixie Chicks eBay auctions. Before the controversy, most of the really great tickets were getting anywhere from $750-1500/pair, and even crappy ones were getting $400-500. Now only the VERY BEST tickets, like in the first couple of rows, can pull down a couple hundred bucks, and most are going for less than face value or not getting a single bid at all.
There simply is no better proof that the Chicks have lost and the author of this article is a bald-faced liar. If those tickets were refundable, or Fatalie had barfed her hate before the tickets went on sale, they'd be playing to 1/4-full stadiums.
And they WILL be next time.
