The Beatles’ Last Song

After their disbandment in the late 1960s, The Beatles left an indelible mark on the music world, with their catalog of timeless classics. However, their creative journey didn’t end there. In November 2023, The Beatles released what they refer to as their “last song,” titled “Now and Then.” This track features the vocals of the late John Lennon, who tragically passed away in 1980. What sets this release apart is the innovative use of AI technology to bring Lennon’s voice back to life.

The Role of Artificial Intelligence

To understand how AI was utilized in the creation of “Now and Then,” we delve into the collaborative efforts of director Peter Jackson, producer Giles Martin, and the remaining Beatles members, Paul McCartney and Ringo Starr. Jackson, known for his comprehensive Beatles documentary “Get Back,” developed software that enabled the team to isolate Lennon’s vocals from the original cassette tape recording of “Now and Then” from the late 1970s.

Using machine learning algorithms, the software could separate the different components of the track, effectively uncoupling Lennon’s vocals from the piano accompaniment. This breakthrough technology allowed the team to work with Lennon’s recorded voice and create a brand new Beatles song.

The Creation Process

The creation process of “Now and Then” involved a combination of AI-assisted vocal separation and the collaboration of the surviving Beatles members. Paul McCartney, upon learning about Jackson’s innovative technology, decided to send Lennon’s original cassette to the team. This marked the beginning of a musical journey that would capture the essence of The Beatles’ sound and style.

Giles Martin, a co-producer of the track, explained how AI was used to recognize and extract voices from a recording. The AI algorithm was trained to distinguish between different voices, allowing the team to isolate Lennon’s vocals from the background noise and instrumentals. With Lennon’s voice restored, McCartney and Starr contributed their instrumental talents, creating the signature Beatles sound that fans know and love.

The Impact of AI on Music Creation

The use of AI in music creation opens up a world of possibilities for artists and the music industry as a whole. Beyond restoring old recordings, AI can be utilized to enhance and transform music in various ways. For instance, AI algorithms can autotune vocals, adjust pitch, or even replace real voices with synthetic ones. While this presents exciting opportunities for experimentation and innovation, it also raises concerns about the potential replacement of human musicians.

Paris Smaragdis, a professor at the University of Illinois Urbana-Champaign and AI consultant for The Beatles project, highlights the historical context of AI-assisted music restoration. He draws parallels to early audio engineers’ efforts to recover recordings of renowned singers like Enrico Caruso. These endeavors aimed to extract the singers’ voices and use them alongside live orchestras. Similarly, AI allows for the preservation and utilization of artists’ voices long after they have passed away.

The Commercial Potential and Future Implications

The release of “Now and Then” by The Beatles sparks a series of important questions about the commercial potential and future implications of AI-assisted music creation. Can this method be replicated for other deceased musicians, providing new avenues for monetization for those who own the rights to their music? Will we see a flood of posthumous releases from beloved artists in the near future, and will there be a demand for them?

While the use of AI in music creation offers exciting possibilities, there are concerns about the loss of authenticity and the potential dilution of an artist’s legacy. Many musicians express reservations about how their audience might perceive music created with AI assistance. The fear of losing the unique and evolving nature of musicians’ work raises doubts about the commercial appeal of AI-generated music.

Paris Smaragdis acknowledges the importance of musicians’ evolution and their ability to surprise audiences. Music is inherently designed to embrace new technologies and incorporate them into its fabric. However, the question remains whether AI-generated music can truly capture the essence of an artist’s creativity and continue to inspire and surprise listeners.

The Future of AI in the Music Industry

The use of AI in the creation of “Now and Then” by The Beatles represents a significant milestone in the integration of technology and music. As AI continues to advance and evolve, its impact on the music industry will undoubtedly grow. However, striking a balance between innovation and maintaining the integrity of musical artistry will be crucial.

Artists, industry professionals, and audiences will need to navigate the ethical and creative implications of AI-assisted music creation. While AI can provide tools for restoration and enhancement, it is essential to preserve the authenticity and human touch that define the magic of music.

As we move forward, it will be fascinating to witness the ways in which AI shapes the future of music creation, distribution, and consumption. The possibilities are vast, and only time will tell how AI will revolutionize the industry while honoring the rich legacies of artists like The Beatles.


The release of The Beatles’ “Now and Then” showcases the transformative power of AI in the music industry. By leveraging cutting-edge technology, the band was able to bring John Lennon’s vocals back to life, creating a remarkable new song. This achievement opens up avenues for exploring the potential of AI in music restoration, creation, and beyond.

While AI offers exciting possibilities, it also raises important questions about the future of music and the preservation of an artist’s legacy. As technology continues to advance, it is crucial to strike a balance between innovation and maintaining the authenticity and human touch that make music so special.

The story of “Now and Then” serves as a testament to the enduring influence of The Beatles and their willingness to embrace new technologies. It also serves as a reminder of the incredible impact that music can have on our lives, transcending time and boundaries.

As we look to the future, we can only imagine the creative possibilities that AI will unlock and the ways in which it will shape the music industry. One thing is certain: The spirit of innovation and artistic expression will continue to thrive, guided by the timeless melodies and revolutionary spirit of bands like The Beatles.
