The UFO Club was founded by John Hopkins (usually known as "Hoppy") and Joe Boyd in an Irish dancehall called the "Blarney Club" in the basement of 31 Tottenham Court Road, under the Gala Berkeley Cinema. It opened on 23 December 1966. Initially the club was advertised as "UFO Presents Nite Tripper". This had been because Boyd and Hopkins could not decide on "UFO" or "Nite Tripper" as a name for their club. Eventually they settled on "UFO". Soft Machine and Pink Floyd were booked for the first two Fridays, and then re-engaged as the club carried on into 1967 after its initial success. Initial events combined live music with light shows, avant garde films and slide shows, and dance troupes. Pink Floyd's tenure at UFO was a short run. As their fame grew they were able to play bigger venues for higher fees. Boyd protested that their increasing fame was largely due to the success of UFO, but the band's management wanted to move on and an agreement was made for just three more Floyd performances at UFO, at an increased fee. Hopkins and Boyd had to cast around for a new "house band" for UFO. They settled on Soft Machine but also started booking other acts who were attracted by the club's reputation. Amongst them were The Incredible String Band, Arthur Brown, Tomorrow, and Procol Harum, who played there when "A Whiter Shade of Pale" was No 1 in the charts.
