Paul McCartney addresses confusion and concerns over AI use in Beatles' "new" song.

Paul McCartney clarified on social media that the Beatles' final song, set to be released this year, was not "artificially or synthetically created" with AI, but rather a demo recording of John Lennon's voice was cleaned up using AI to separate it from background music. McCartney and Ringo Starr are the only remaining members of the band, and it is possible that the recording used for the new song is from a demo tape Lennon made in 1978 called "Now and Then."
