BOSTON -- Boston is marking Independence Day, and its rich Revolutionary War history, with music, fireworks and fighter planes.

On Saturday, people were filling the banks of the Charles River to grab seats for the free annual Boston Pops concert that evening, featuring singer Neil Diamond.

The concert kicks off with the national anthem and a flyover of the Air National Guard's 104th Fighter Wing and the Air Force's 131st Fighter Squadron. It ends with a nationally televised fireworks display.

Saturday morning saw the Navy's oldest commissioned warship, the USS Constitution, perform its annual turnaround in Boston Harbor. "Old Ironsides" fired a 21-gun salute and 19-gun salute along the way.
