Remember how XM and Wal-Mart teamed up to benefit the Children's Miracle Network? Well here's a new TV spot that will air on Wal-Mart video monitors in retail stores.

The first XM Kids Roadshow broadcast and live concert will be in Los Angeles on April 30th. The channel will broadcast from the road every day and host fund-raising events at select Wal-Mart locations to help raise $10 million in just 30-days for Children's Miracle Network.
