The actual weather in Washington was cloudy and misty, making it quite difficult to view the fireworks. But on "A Capitol Fourth," the annual concert special that airs live from the West Lawn of the U.S. Capitol, many of the fireworks (primarily in the second half of the display) looked glorious in a clear sky.

As soon as the show ended, producers from Capital Concerts owned up to the fact that not all of its footage was from the live fireworks show.
