In the swinging sixties, Eel Pie Island in south west London was turned from a mellow 'secret' home to a few locals into a mini festival location. Invaded by teenagers, then mods, rockers and hippies, as rhythm n blues slowly turned into heavy rock. This is (part of) the story of how Pink Floyd, The Who, Deep Purple, Black Sabbath, Free, Genesis & Mott the Hoople all showed up and carried their gear across a rickety wooden footbridge to a hippy island haven.
