“Citing poor ticket sales during the week of the Republican National Convention, two more Broadway shows have announced that they will close to avoid a dismal week of business. ‘Caroline, or Change,’ the new musical by Tony Kushner, which was nominated for six Tony Awards this year, will close on Aug. 29, the day before the start of the convention, and ‘Frozen,’ a play by Bryony Lavery that was nominated for four Tonys, will end its run on Aug. 22, the shows’ producers said yesterday.”
