The world can hear one final Beatles song. On Thursday, the legendary band released their last new tune, “Now And Then,” which was developed with the help of an AI program. 

The song is now streaming, and as you’ll hear, Beatles member John Lennon’s voice sounds fully revived as he sings about trying to win back a lost lover. 

Lennon actually recorded “Now and Then” as a demo, featuring his voice and piano-playing, before his death over 40 years ago. In 1994, the cassette tape of the track was then passed to the remaining Beatles members, who had originally wanted to build a full song off the demo. But the audio’s poor quality derailed the effort, with Beatles member George Harrison reportedly calling the tune “rubbish.”

In a documentary the band released yesterday about “Now and Then,” Beatles member Paul McCartney recalls the resistance to finishing the song. “Wait a minute,” McCartney remembers thinking. “Let’s say I had a chance to ask John, ‘Hey John, would you like us to finish this last song of yours?’ I’m telling you, I know the answer would have been: ‘Yeah.’ He would have loved that,” McCartney says. 

The documentary also shows footage from the mid-1990s of the band trying to record a song with the demo. But at the time, the band didn’t possess the technology to separate Lennon’s voice from the piano-playing, resulting in some distortion. “When we started ‘Now and Then,’ John was sort of hidden in a way,” Beatles band member Ringo Starr recalls.

“Every time we wanted a little bit more of John’s voice, this piano came through and clouded the picture,” McCartney added. So the group abandoned the project. In 2001, Harrison then passed away, making it seem like “Now and Then” would never be completed.

That changed in 2022. A year before, director Peter Jackson had released the documentary The Beatles: Get Back, which featured old footage of the band’s rehearsals from 1969. 

To improve the footage’s audio, Jackson used a “machine learning system” that can seemingly learn to replicate the sounds of an instrument or a voice. The result was able to de-mix the mono soundtrack of the original footage, separating the individual voices and instruments for a clearer quality.

“We thought, well we better send John’s voice to them off the original cassette,” McCartney said. “And there it was, John’s voice, crystal clear.”

“So in the mix, we could lift John’s voice, without lifting the piano, which had always been one of the problems” he added. “Now we could mix it and make a proper record.”

To finish the song, McCartney recorded bass, guitar and piano, while Starr added a new drum part. Electric and acoustic guitar tracks that Harrison recorded back in 1995 was able to complete the song, ensuring all members had made a contribution. “Wow, this is it, now it’s a Beatles record,” McCartney said.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
