Watch the Air Force Band Flash Mob Guests at the Smithsonian

One can only imagine what it must have been like to witness this beautiful moment in person. Not only was it a great holiday surprise, it was also a breathtaking performance by an incredibly talented group of men and women.

The United States Air Force Band wanted to bring some holiday cheer to visitors at the Smithsonian's National Air and Space Museum. So, starting with a single cellist, more and more musicians joined in, swelling to a total of 120 band members.

What you will hear is a four-minute arrangement of "Jesu, Joy of Man's Desiring/Joy to the World." Enjoy, and Merry Christmas from the United States Air Force Band.
