Under the auspices of the department of physical education, the José Limón Dance Company presented a master class and a concert featuring four pieces set to the music of Vivaldi, Pergolesi, Purcell and contemporary American composer Norman Lloyd.  "This is not easy dancing to watch," Imogene Howe '60 wrote in The Miscellany News.  "It makes heavy demands upon the viewer's concentration.  He does not know what is going to happen next in this choreography; surprise follows surprise."
