The band had worked on ten songs, including both sides of the upcoming single, by 1 May, when they interrupted the sessions to perform at the "NME" annual Poll-Winners Concert. At a time when "Time" magazine dubbed London "the Swinging City", belatedly recognising its ascendance as the era's cultural capital, the Beatles drew inspiration from attending concerts by visiting artists, as well as film premieres, plays and other cultural events. From February through June, these musical acts included Stevie Wonder, Roy Orbison, the Lovin' Spoonful, the Mamas & the Papas, Bob Dylan (with whom they socialised extensively), Luciano Berio and Ravi Shankar. During mid-May, Lennon and McCartney attended a private listening party for the Beach Boys' "Pet Sounds" album, and McCartney met Italian director Michelangelo Antonioni, who filmed "Blowup" in London, inspired by the contemporary fashion scene.
