I think it was in the '' Back In '72 '' time when massive groups of people went to what was billed as '' Kite-in '' at Belle Isle I remember going to 2 of them , early spring when people would get out and go to Belle Isle and fly kites . People would bring picnic stuff , beer , wine , and other goodies . One year Bob Seger gave a short but free concert at the Kite-in and I remember him doing Back In '72
