The Beatles have released their last song, called "Now and Then". It was written by John Lennon. Other Beatles members added to it over the years. Engineers used AI to bring the song to life. It sounds like the Beatles recorded it in a studio. The song has been released as a single. The other side of the single is a new mix of 1962's "Love Me Do". "Now and Then" is the final track on a new edition of the Beatles' greatest hits "blue" album.

Paul McCartney said recording the new song was "emotional". He said: "It's a genuine Beatles recording." He added: "To release a new song [in 2023] the public haven't heard is an exciting thing." McCartney said John Lennon's voice was "crystal clear". Lennon was shot dead by a fan in 1980. Beatles drummer Ringo Starr said the song was, "the closest we'll ever come to having [John Lennon] back in the room".
