John “Hoppy” Hopkins was the co-founder of at least three underground projects: International Times magazine; a fabled but short-lived music venue called the UFO Club; and the London Free School, a community-based adult education initiative.

During the couple of years up to June 1967, when Hoppy was jailed for cannabis possession, Britain’s fertile and diverse counterculture took much of its inspiration from him, and he was the closest thing the movement ever had to a leader.
