After los­ing her voice on her “2012 Blown Away Tour” recently, Car­rie Under­wood plans to donate the pro­ceeds of her Des Moines con­cert to char­ity. Under­wood didn’t can­cel the Decem­ber 14th show com­pletely, though. In fact, she per­formed for more than 90 min­utes. “I’m giv­ing a mil­lion per­cent, but I’m still only get­ting to about half of where I want to be, and I’m not used to that,” she admit­ted to the crowd.
