A local father-son duo is a big part of People Light’s World Premiere retelling of Charles’ Dickens A Christmas Carol. Swarthmore resident Zak Berkman, People’s Light’s Producing Director, has adapted this yuletide ghost story into a music infused tale that captures the magic, joy, and generosity of the beloved classic in a whole new light. Berkman’s 16-year-old son, Eliot Berkman-Lamm plays guitar as well as several characters.
