This event by Ono - she preferred event to 'happening' - was promoted by Art School lecturer Dave Clapham and attracted a sold-out audience to Bluecoat. The programme, Music of the Mind and the world premiere of The Fog Machine, was filmed by Granada TV for a news feature. It shows a packed Concert Hall and enthusiastic response to this Fluxus event by the, then, little-known Ono, who returned to Bluecoat for its reopening in 2008. Photo: Sheridon Davies.
