Sitting in my student, back-to-back house in Beeston, Leeds in the early 80s, I experienced an extraordinary sonic phenomenon: 40,000 voices raised in a vast cheer burst into the sitting room, followed by urgent chanting and a massively disappointed “ohhh..” It was unexpected (did I even know there was a football ground nearby?) and chilling yet very moving. These voices, raw, in atavistic unison impinged on the mundane activities of my everyday life. This surreal incongruity of hearing but not seeing the source of so many voices erupting uninvited into my house occurred on many subsequent Saturdays and I came to quite enjoy the unsolicited mass companionship. The memory has stayed with me ever since.
