Before her Backwoods Barbie album arrived in stores earlier this week, the glittered goddess of country music, Dolly Parton, postponed her Chicago shows. The trouble? Back pain. Insert your own witty punchline here. On second thought, that won't be necessary. In a statement released about the cancelled tour dates, the well-endowed singer explained, "Hey, you try wagging these puppies around a while and see if you don't have back problems." Zing. Never one to disappoint fans, Dolly has already rescheduled the Chicago Theatre dates for May 8^th and May 9^th.
