Here are four of the videos for "We Can Work It Out". Three of them were "promotional films" (these days they call them "music videos"), produced by Tony Bramwell and directed by Joe McGrath, and were filmed at Twickenham film studios by the Intertel company. The one in the lower right corner is a different story, it's from "The Music of Lennon and McCartney" which Johnnie Hamp produced for Granada TV together with the Beatles' company SubaFilms.
Johnnie Hamp: "I chose 'We can work it out' and 'Day Tripper' from about a dozen tracks which John and Paul played to me in Brian's flat. The other tracks went on to Rubber Soul - all everlasting songs".
