Thania Garcia What year is it again? The Beatles have charted a top 10 single on this week’s singles chart with “Now and Then” — otherwise known as “the last Beatles song.” The “new” song, which features all four members, including the late John Lennon and George Harrison, hit No. 7 as the band’s first chart-topper on the Hot 100 in nearly 30 years. Through the use of AI technology, Lennon’s isolated vocals served as the foundation for the single that was eventually completed last year by Paul McCartney, Ringo Starr and co-producer Giles Martin, with the addition of Harrison’s 1994 guitar tracks.
