Writer Peter Rothstein conceived All is Calm: The Christmas Truce of 1914 as a radio piece, and first presented it as a concert with nine singers and three actors in a church auditorium in 2007. Rothstein used the soldiers' own words, and Erick Lichte and Timothy C. Takach arranged the 30-or-so songs, including traditional carols, popular tunes of the day, and songs which had emerged from the war itself. The show takes only an hour, but there is much to absorb and appreciate.
