On Christmas Eve, 1920, John Meredith Langstaff was born into a music-filled home where a rousing carol party was the peak of his family's year. Half a century later, his inspired Christmas Revels was born, a theatrical weaving of diverse traditional song, folk dance, and drama that has become a beloved institution across the country. Now award-winning author Susan Cooper, a long-time writer for the Revels, traces its roots through the rhythms of Jack Langstaff's life - from his days as a star choirboy to his early career as a noted recital singer; from a daunting World War II injury to his work as recording artist, TV performer, teacher, and children's author. Along the way, his passion for music, ritual, and community fused to spark the incomparable Revels, a participatory celebration that promises to draw children of all ages for even more generations to come.
