Photojournalist John Hopkins captured many aspects of London's cultural revolution of the late '60s, including Beat Poetry, LSD, the Rolling Stones, anti-nuclear rallies and East End slums. (In his spare time, he also hosted bands such as Pink Floyd at his UFO nightclub and co-founded The International Times.) The Idea Generation Gallery exhibits Hoppy's photographs of gigs, rallies, tattooists and prostitutes, portraits of Dizzy Gillespie, Malcolm X and Alan Ginsberg and a number of original promotional posters.
