The last Beatles song, the “Now and Then”, topped the UK charts, which happens for the first time in 54 years for the legendary group, according to the organization that collects the sales data.

The song was released last Thursday. An early version of it was recorded in 1978 by John Lennon, but it was completed after his death by fellow band members Paul McCartney, George Harrison and Ringo Starr, and now, years after Harrison’s death, it has been completed thanks to Artificial Intelligence.

The last time a Beatles song was found on top of the UK weekly chart was in 1969, with the “The Ballad of John and Yoko”The Official Charts Company said in a statement declaring “officially” the “return of Beatlemania.”

In total, the Liverpool band, who broke up in April 1970, saw 18 of their songs reach the top of the charts.

“It’s shocking. I’m stumped. It’s a very emotional moment for me,” said the 81-year-old Paul McCartney.

“Now and Then” was recorded by Lennon in his apartment in the late 1970s. After his assassination in 1980, his widow, Yoko Ono, gave this recording, which featured only the piano and his voice Lennon, to the rest of the band.

Recently, thanks to artificial intelligence, it became possible to isolate Lennon’s voice and then mix it with the other members’ voices and music.

The reception of the song by the press however she was not effusive: the Washington Post called it “banal” while the Times wrote that it “cannot be considered a lost masterpiece”.
