Short answers, pulled from the story.
Revolver was released on the 5th of August 1966 in the United Kingdom and on the 8th of August 1966 in the United States. It was accompanied by the double A-side single “Eleanor Rigby” and “Yellow Submarine”.
The original UK version of Revolver contains 14 tracks. Capitol Records reduced the North American version to 11 songs, omitting three Lennon-written tracks, “I’m Only Sleeping”, “And Your Bird Can Sing”, and “Doctor Robert”, which were instead placed on the June 1966 US release Yesterday and Today.
The cover was designed by Klaus Voormann, a German-born bassist and artist who had been a friend of the Beatles since their early days in Hamburg. It combined Aubrey Beardsley-inspired line drawings with photo collage and won the 1967 Grammy Award for Best Album Cover, Graphic Arts.
Revolver introduced nine recording techniques, according to Kevin Ryan and Brian Kehew, including automatic double tracking (ADT), which EMI engineer Ken Townsend invented on the 6th of April 1966, backwards recording, and close-miked drums. The album also featured the first pop use of a vocal recorded through a Leslie speaker cabinet and the first deliberate backwards guitar solo composed to be heard in reverse.
Revolver is a pun referring both to a type of handgun and to the revolving motion of a record playing on a turntable. The Beatles had originally wanted to call the album Abracadabra but discovered another band had already used the name; they confirmed the final title by telegram from the Tokyo Hilton on the 2nd of July 1966.
In the UK, Revolver entered the Record Retailer chart at number 1 and remained there for seven weeks during a 34-week run in the top 40; on the Melody Maker national chart it held number 1 for nine weeks. In the US, it reached number 1 on the Billboard Top LPs chart on the 10th of September and stayed there for six weeks, and had sold more than 1.7 million copies in the country by the end of the decade, according to figures published in 2009 by former Capitol executive David Kronemyer.
