More than 50 years after The Beatles broke up, the surviving members of the British band have announced the release of their last song called Now and Then based on a 1970s demo recording by the late John Lennon.

Now and Then will be made available to the public on November 2. Sir Paul McCartney and Sir Ringo Starr completed the song last year with the help of artificial intelligence (AI). Among the other members of the band, Lennon was shot dead by a fan in 1980 and George Harrison passed away in 2001.

“NOW AND THEN. THE LAST BEATLES SONG. OUT 02.11.23. #NowAndThen. New expanded and mixed editions of the Red and Blue albums to be released 10.11.23,” the official handle of The Beatles wrote on X.

The announcement was accompanied by a 34-second-long video that chronicles the history behind Now and Then. John Lennon’s widow, Yoko Ono, handed over Lennon’s original recordings to his former bandmates who embarked on the task of working on these tracks. However, they encountered a significant hurdle in the form of the home recording, which could not be properly mixed using the audio technology available at the time. It wasn’t until last year that McCartney and Starr revisited the project and managed to complete Now and Then by harnessing the capabilities of cutting-edge AI.

To celebrate the release, Now and Then will be accompanied by a 12-minute making-of documentary on the day before its official launch as well as a music video the day after. Additionally, the track will be paired with The Beatles’ 1962 debut single Love Me Do as a double A-side single, featuring an original cover designed by the renowned artist Ed Ruscha.

Now and Then will also be included in the expanded reissue of the Beatles’ greatest hits collections, 1962-1966 (commonly referred to as The Red Album) and 1967-1970 (The Blue Album), both set to hit the shelves on November 10.
