(CNN) The show must go on in New York, even if parts of Manhattan have lost power, forcing the evacuation of Broadway theaters and sending tens of thousands of people onto darkened streets.

The cast of the Broadway musical "Hadestown" took their show to the road, literally -- performing outside the Walter Kerr Theatre for fans.
