This is Comedy in the Dark, a late-night comedy revue at the Gilded Balloon performed, as the title indicates, with the lights off. It’s one of a number of Fringe venues and shows forging an unlikely link between comedy and the green agenda. At the (Almost) Carbon Neutral Comedy Club, at the Counting House, comics perform without microphones, and all flyers are printed on recycled paper and must be recycled at the end of the festival (the “almost” has crept in because some lights are kept on). And at the Pleasance Courtyard, a large, brightly painted ark – made of reclaimed materials and powered, in part, by children energetically riding a small, bicycle-driven dynamo – is providing an unusual, eco-friendly venue for children’s comedy and storytelling.
