Stephen Thompson on the biggest surprises, trends and questions to be found in the Grammy nominations, plus the most interesting stories to be found beyond the major categories.

Paul McCartney and producer Giles Martin used artificial intelligence to isolate John Lennon's vocals from an old demo to finally complete The Beatles' "last" song, "Now And Then."

Lennon suggested that the song represents "our collective desire for peace worldwide" and that it transports listeners to a place "where love and togetherness become our reality."

The new three-part Disney+ docuseries Get Back is a true treasure. It offers an inside look at The Beatles' creative process, as well as amazing footage from their legendary rooftop concert.

The forthcoming documentary Get Back revisits The Beatles' final days together. McCartney says he took the band's breakup hard: "It was quite difficult, because I didn't know what to do at all."

The 33-minute recording captures Lennon and Yoko Ono talking to student journalists during their 1970 stay in Denmark. He also sings "Radio Peace," a song that is not believed to exist anywhere else.
