The Fool were a Dutch design collective led by Marijke Koger and Simon Posthuma, best known for their work with the Beatles, which included designing the tunics the band wore for their 1967 television broadcast of All You Need Is Love, decorating John Lennon's piano and George Harrison's Mini, painting a circular mural at the Harrisons' Surrey home Kinfauns, designing the inner sleeve of the Sgt. Pepper's Lonely Hearts Club Band LP and, most famously, painting a three-story psychedelic mural on the facade of the Beatles' short lived Apple Boutique in London's Baker Street, which was subsequently painted over by order of the local council. Pattie Boyd and her sister Jenny were fans of the collective and would model their clothing designs for the Apple Boutique. According to Boyd, this brocade ensemble was custom made for her by The Fool and she recalls wearing it during a trip to Greece with all four Beatles in July 1967 to explore the possibility of buying a set of Greek islands.
The first time Yoko spoke out at full volume during a recording session it was to convey some relatively trivial word of advice to John about whatever he was singing at the moment. The other Beatles looked around, straight-faced, startled, stunned. There was a moment's dead silence that was broken by Paul: "Fuck me! Did somebody speak? Who the fuck was that?" Of course he knew full well who had spoken. The others joined in: "Did you say something, George? Your lips didn't move!" "Have we got a new producer in?"
