On Friday, July 4th, join PBS and celebrate our country’s 249th birthday live from the West Lawn of the U.S. Capitol with all-star musical and patriotic performances from a variety of artists plus the greatest display of Independence Day fireworks anywhere in the nation lighting up the iconic D.C. skyline! One of those amazing performers on "A Capitol Fourth" is Josh Turner, who’ll be singing his new single, "Unsung Hero."
