The Beatles release their last new song "Now and Then" — thanks to AI and archival recordings

The last "new" Beatles song, "Now and Then," was released on Thursday, 60 years after the onset of Beatlemania. 

The fresh release features the voices of all four original Beatles performers, with surviving members Paul McCartney and Ringo Starr essentially finishing what was initially an old demo recording by John Lennon. The track draws in many ways on group's signature style and features emotional chorus where, together, McCartney and Lennon's voices sing, "I miss you."

The original "Now and Then," recorded by Lennon more than 40 years ago, came from the same group of demo recordings that his former bandmates used to create the songs "Free As a Bird" and "Real Love" in the mid-90s.
