tour, Lennon opted for Four Sides to the Circle in response to McCartney's Magic Circle, and Starr jokingly suggested After Geography, a play on the title of the Rolling Stones' recently released Aftermath LP. Other suggestions included Bubble and Squeak, Beatles on Safari, Freewheelin' Beatles and Pendulum before the band settled on Revolver. They confirmed their choice in a telegram to EMI, sent from the Tokyo Hilton on 2 July. Release In mid May 1966, Tony Hall of Record Mirror wrote a preview of the Beatles' new recordings in which he opined that some of them were "the most revolutionary ever made by a pop group". While avoiding mention of the official song titles, he highlighted Lennon's "The Void" for its electronic effects, along with a "McCartney song about lonely people" set to string orchestration, and a "Harrison number on which he plays a long exotic solo on sitar". In Britain, EMI gradually distributed the album's songs to radio stations throughout July – a strategy that MacDonald describes as "building anticipation for what would clearly be a radical new phase in the group's recording career". Revolver was released there on 5 August and on 8 August in the United States. "Eleanor Rigby" was issued as a double A-side single with "Yellow Submarine". The pairing of a ballad devoid of any instrumentation played by a Beatle and a novelty song marked a significant departure from the usual content of the band's singles. Schaffner likens the Beatles' 1966 recordings to the moment of transformation in the film The Wizard of Oz, "where, when Dorothy discovers herself transported from Kansas to Oz, the film dramatically changes from black-and-white to glorious technicolor". The album appeared a year before psychedelic drugs became a phenomenon in youth culture, and it was the source of confusion for the group's more conservative fans. A female writer later complained in Beatles Monthly that 1966 represented the end of "The Beatles we used to know before they went stark, raving mad". In this way, Revolver marked the start of a change in the Beatles' core audience, as their young, female-dominated fanbase gave way to a following that increasingly comprised more serious-minded, male listeners. The release coincided with a period of public relations challenges for the band, the combination of which led to their decision to retire from touring following the end of their North American tour, on 29 August.
