Tracy Byrd plays for free

The retailer will recognize the U.S. community that sells the most miracle balloons at Wal-Mart Stores, Neighborhood Markets, Distribution Centers and Sam's Club locations during the month of May with a free, live concert performance by Byrd, a longtime supporter of Children's Miracle Network and contributions to his hometown children's hospital in Beaumont, Texas.

With less than two weeks left, the communities currently leading the competition are: *Marietta, Ohio, Athens, Ga., Fort Smith, Ark., Charleston, S.C., Sioux Falls, S.D., San Jose Decatur, Ill., Baton Rouge, La., Kissimmee, Fla. and Pascagoula, Miss.

"If every person who shops at Wal-Mart or Sam's Club purchased just one balloon, together we could really help improve the health and welfare of children through Children's Miracle Network," Byrd said. "I'm looking forward to celebrating with the community that gives the most back."

The balloons cost $1 each at Wal-Mart stores.
