The PA Classes of of 1970, 71 and 72 capture the spirit of the late 60s with these poignant photos of several peace rallies in Times Square, Bryant Park, and Columbus Circle in the winter and early spring of 1970, attended by such recognizable faces as Pete Seegar, Tom Paxton, Peter Paul and Mary, Hair composer Jerome Ragni, and Ossie Davis...

Here's Mack's recollections: "Yes the pictures of PA students marching was one rally that ended at Columbus circle with a PA dramatic antiwar presentation. My recollection is that all of these events took place in winter/spring of 1970. the pix of celebs at times square was another event. we were one of many schools informally participating along with the general public. it was a "Broadway" antiwar rally. Because of us being PA, the organizers specifically reached out to us to participate. the celeb pix with the long hairs and the black guy was Rado or Ragni, the writer/producers of HAIR and one of their cast members. they were singing "Let the sun shine in"; the kid running through the park alone by the NY Public library is me, snapped by a "girl friend". The PA'ers taking part in the demonstrations were from all departments, from classes of 1970, 71 and 72."
