Known as “United States Vocal Ambassadors to the World,” the eight-part harmony, a cappella group Voices of Liberty performs daily at Epcot and is known for American classics as “Oh! Susanna,” “My Country, ‘Tis of Thee,” and “Skip to My Lou.” I personally love seeing them perform during this time of year when the group gets out their holiday songbook.

Here’s a video of Voices of Liberty performing a mash-up of the holiday carols, “Hark! The Herald Angels Sing” with “Angels We Have Heard on High.”
