4/5/71: show number two of a three night stand—billed as the grateful dead dance marathon—was held at the manhattan center, a small, multi-purpose venue located on west thirty-fourth street in new york city. the manhattan center ballroom had aquamarine walls covered with murals on various social themes. under one of the largest of these murals read, ‘for the furtherance of industry, religion, and the enjoyment of leisure.’ the dance marathon fell, presumably, under the heading of leisure, although there certainly might have been a religious angle to be found somewhere. five bucks a pop.
