Poster for Yoko Ono performance

In the 1960s, Bluecoat Society of Arts set up Bluecoat Arts Forum to promote the arts on Merseyside. With the arrival of Wendy Harpe, the programme became more adventurous, encompassing experimentation in performance, visual art, music and poetry. Yoko Ono's 1967 event was promoted by Art School lecturer Dave Clapham and attracted a sold-out audience. 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 an enthusiastic response to this Fluxus event by the, then, little-known Ono, who returned to Bluecoat for its reopening in 2008.
