John Sinclair hailed from Flint, Michigan. He was the manager of Detroit’s MC5 and a poet himself. He was imprisoned in 1969 for selling two joints to an under-cover narcotics agent. He became internationally known when John Lennon and Yoko Ono headlined this show in 1971. Twenty thousand people turned out at the University of Michigan to tune out. Lennon played his song “John Sinclair.” The Michigan Supreme Court released Sinclair three days after the concert.
His conviction was later overturned.
