AI enables release of final Beatles song with John Lennon's voice, says Paul McCartney.

The Beatles will release a new song this year featuring vocals from John Lennon, with the help of artificial intelligence. The band used cutting-edge technology to extract Lennon's voice from an old demo recording, and the so-far unnamed song will be the band's first original material since the release of "Free as a Bird" and "Real Love" in 1995 and 1996. The song is likely to be "Now and Then," a Lennon composition made around the same time as his "Free as a Bird" and "Real Love" demos.
