The United States Naval Academy Ceremonial Patriotic Band plays "Anchors Aweigh" during an outdoor concert at the Inner Harbor Amphitheater held during the Star-Spangled Spectacular. The Star-Spangled Spectacular celebrates the bicentennial of the Battle of Baltimore which provided the backdrop for Francis Scott Key's famous poem, "Defense of Fort McHenry," which later became America's national anthem. More than 30 ships from the U.S. and foreign nations, and the U.S. Navy's Blue Angels aircraft will be on display and open to the public.
