"Hark! The Herald Angels Sing." Is there something happening in the "Little Town of Bethlehem"? "Mary, Did you Know?" that "The First Noel" would become the basis for a body of music known today as Christmas carols? The birth of Jesus may have occurred roughly 2,000 years ago, but the music associated with his birth and the celebration of Christmas did not evolve for another millennia. Why did the evolution take so long? What forms did it take, and are those forms still evident in traditional carols today? Join Jane and Bobbie for "Twelve Days of Christmas" as we answer these questions.
