Along with a celebration of the Solstice, you'll hear an interview with legendary songwriter John McCutcheon, an icon in traditional and topical folk music, right up there with Pete Seeger and Arlo Guthrie. His song "Christmas in the Trenches," based on the Christmas Truce of World War I in 1914, is one of the most treasured seasonal songs of any genre and is an amazing tribute to the power of music. Hear in his own words how he came to write this beloved ballad. You'll also hear from Vietnam vet and historian Bill Hutchinson, who has his own story to tell about how an unexpected song saved his life in Vietnam.   Celebrate the songs of light from Peter Mayer, Dancing Light Duo, and Megan McDonough as well on The Traveler: Healing Journeys Through Music.
