The Beatles’ “Now and Then”: A Bittersweet Reunion Through the Power of AI
More than five decades after their breakup, The Beatles stunned the world once again with the release of what is now widely considered their final song—“Now and Then.” Released in November 2023, this emotional track brought together the legendary voices and musical talents of John Lennon, Paul McCartney, George Harrison, and Ringo Starr one last time. What made this reunion even more remarkable was not just the music itself, but the groundbreaking role artificial intelligence (AI) played in making it possible.
Origins in a Lennon Demo
The story of “Now and Then” begins in the late 1970s. John Lennon recorded a rough demo of the song at his apartment in the Dakota building in New York City. The recording, like many of his home demos, was intimate and heartfelt—but far from studio quality. The audio included both Lennon’s vocals and his piano playing, captured on a basic cassette tape with background noise and technical imperfections.
Following Lennon’s tragic death in 1980, his widow Yoko Ono handed over the tape—containing “Now and Then” along with other demos like “Free as a Bird” and “Real Love”—to the remaining Beatles in the 1990s. As part of their Anthology project, Paul McCartney, George Harrison, and Ringo Starr attempted to finish these unfinished works as a tribute to Lennon. They successfully completed “Free as a Bird” and “Real Love,” which were released in 1995 and 1996, respectively. However, “Now and Then” was shelved due to the poor quality of Lennon’s vocal recording. The trio struggled to separate Lennon’s voice from the piano and background noise, and the technology at the time simply wasn’t up to the task.
A New Era of Technology
Fast-forward to 2021, when director Peter Jackson released the acclaimed documentary series The Beatles: Get Back. During the making of this project, Jackson’s team developed revolutionary audio restoration software using machine-assisted learning (a form of AI) to isolate vocals and instruments from mono recordings. This same technology caught the attention of Paul McCartney and Ringo Starr.
With this advanced AI-based tool, they revisited “Now and Then” and were finally able to extract Lennon’s vocals cleanly from the original cassette demo. The AI wasn’t generating Lennon’s voice artificially—it was enhancing and isolating his real performance from the background sounds. This distinction was crucial for fans who feared the song would rely on synthetic vocals.
The resulting vocal track was hauntingly clear, revealing Lennon’s emotive delivery and intimate tone. With his voice finally restored to a usable state, the surviving Beatles got back to work.
Completing the Song
Paul McCartney and Ringo Starr went into the studio and recorded new parts for the song. They were joined, in spirit, by George Harrison, who had recorded guitar parts for “Now and Then” back in the 1990s before his death in 2001. Harrison’s contribution was preserved and integrated into the final version.
The completed track featured McCartney on bass and vocals, Starr on drums and backing vocals, and a delicate string arrangement recorded at Capitol Studios. McCartney also added a slide guitar solo in homage to Harrison’s distinctive style. The final mix, produced by McCartney and Giles Martin (son of Beatles producer George Martin), was both modern and deeply rooted in the band’s classic sound.
Reception and Legacy
Released on November 2, 2023, “Now and Then” was instantly embraced by Beatles fans worldwide. It debuted at number one on the UK Singles Chart and topped charts in several countries, including Germany, marking The Beatles’ first UK number-one hit in over 50 years.
Critics praised the song not only for its emotional weight but also for its tasteful and respectful use of technology. Far from being a gimmick, the AI-assisted restoration was seen as a tool that allowed Lennon’s original artistry to shine through. Many viewed the track as a final chapter in The Beatles’ story—an emotional closure that brought all four members together one last time.
“Now and Then” was also added to the expanded edition of the compilation album 1967–1970 (The Blue Album), released on November 10, 2023, further cementing its place in Beatles history.
Recognition at the Grammys
In a historic moment, “Now and Then” went on to win the Grammy Award for Best Rock Performance in February 2025. It was also nominated for Record of the Year, marking the first time an AI-assisted song received such major recognition from the Recording Academy. The win signaled a growing acceptance of new technologies in the music industry—so long as they serve the authenticity of the art.
No Full AI Album—Yet
While “Now and Then” stands as a testament to what’s possible when old recordings meet new technology, there has been no official announcement of a full Beatles reunion album created with AI. Paul McCartney has confirmed that the song represents the last time The Beatles will be heard together on a new recording. For now, “Now and Then” remains a unique piece of musical history—part farewell, part miracle.
The Beatles have always been pioneers—whether pushing the boundaries of studio technology in the 1960s or embracing modern innovations in the 2020s. “Now and Then” is more than just a song; it’s a bridge across time, a moving testament to friendship, legacy, and the evolving relationship between music and technology. With the help of AI, The Beatles gave the world one last gift—a moment of harmony, nostalgia, and creative brilliance that will echo through generations.
