The U.S. Air Force Band surprised holiday visitors in Maryland at the Gaylord National Convention Center with a “flash mob” Christmas performance. Complete with a full brass band, Irish dancers, and a full choir, the performance, although a surprise, was masterfully choreographed and a complete delight.

The Air Force posted the video online and stated:

The gift of music is a wonderful way to bring together family and friends to celebrate this time of year. The season also reminds us that the freedom we enjoy as Americans remains one of our greatest gifts. To celebrate the start of the 2017 holiday season, we surprised visitors at the Gaylord National Convention Center in National Harbor, Maryland with a surprise performance of “Dona Nobis Pacem” and “We Wish You a Merry Christmas.

This holiday season be sure to thank a veteran and man or woman in uniform. Enjoy the Air Force performance and spread “good will to all men.”
