Audience members, including Elaine Warner, 2, hold their hands over their hearts while the U.S. Air Force Heritage of America Concert Band plays the National Anthem at Williamsburg, Va., July 4, 2012. In addition to entertaining and inspiring onlookers, the band served as a tool to allow for interaction between the Air Force and the public. (U.S. Air Force photo by Tech. Sgt. Barry Loo/Released)
