John Lennon composed and recorded the song 'Now and Then' in New York in the late 1970s. In 2021, Peter Jackson used AI technology applied in his Beatles documentary to restore this song. Paul McCartney and Ringo Starr completed the production of the song this year. It will be released in audio and MV format, alongside the Beatles' first song 'Love Me Do' as a double A-side vinyl. This is referred to as the Beatles' final song, featuring the restored original recordings of Lennon through AI technology.
