The Beatles have released their latest Abbey Road box set teasers, with two versions of the Paul McCartney classic “Oh! Darling” posted online. The audio-only videos are for the new Giles Martin remixed version — and “Take 4,” featuring a bare-bones version of the track, with a “guide vocal” by McCartney.

Set for release on September 27th is the 50th anniversary edition of the group's 1969 swan song Abbey Road. Newly remixed by producer Giles Martin and mix engineer Sam Okell in stereo, high res stereo, 5.1 surround, and Dolby Atmos, the collection is accompanied by 23 session recordings and demos, most of which are previously unreleased. The set will be available on CD, vinyl, and all digital platforms.

Just prior to Abbey Road's September 1969 release, John Lennon was asked where the band found the material for the then-upcoming album: “From a large number of songs, y'see. Each of us have got, y'know, maybe about 10 songs to contribute to an album — you can't get 'em all on. So, when it's your turn to record, as it were, you've got to, sort of, pick the one you want on most, really. It gets into that.”

George Martin's son, Giles Martin explained that his father and the Beatles were only interested in the creative end of recording: “The wanted to push the boundaries of sound. They wanted to create something new all of the time. He was open to anything. There were no rules. The only rules were to make great sounding records.”
