On the dance floor, space has changed. There used 
to be a time when people would dance around doing 
fox trots and waltzes. On the new dance floor this 
doesn’t happen. Space has changed. You couldn’t 
ask anybody doing a frug or a watusi for the next 
dance or for any dance. The dancers make their own 
space, their own world.
