The Grammy had plenty of surprises for viewers yesterday. Aside from Drake winning 5 Grammys (with one being for his massively successful diss track, “Not Like Us”) last night’s event also saw the Beatles take home a Grammy for their song “Now and Then”, which was put together in part by AI. The song beat out other industry luminaries like Green Day, Pearl Jam, The Black Keys, Idles, and St. Vincent.

The win wasn’t because of an AI version of John Lennon – the truth is far more mundane. The song was originally recorded as a rough demo at his New York apartment, and while there have been attempts in the past by the surviving members of the band to publish the song after Lennon’s death, technological limitations prevented them from separating Lennon’s vocals from the lo-fi piano track.

Enter Lord of the Rings auteur Peter Jackson, who developed machine-learning tech that was able to isolate and enhance Lennon’s voice. This finally allowed both McCartney and Starr to finish the track, which is now regarded to be The Beatles’ final song.

According to McCartney, nothing was artificially or synthetically created. AI was simply used to separate, and enhance elements of the song.
