Sir Paul McCartney is clarifying some comments he made surrounding the use of AI on the upcoming ‘final’ Beatles album.

The legendary singer revealed to BBC that AI tech was used to extricate and clean up an old recording of John Lennon’s voice from a previously unheard track. “We just finished it up and it’ll be released this year,” McCartney said in that interview.

During that interview, McCartney revealed that director Peter Jackson was instrumental in getting a clear voice from the old recording. “[Jackson] was able to extricate John’s voice from a ropey little bit of cassette that had John’s voice and a piano,” McCartney explains. “He could separate them with AI—he could tell the machine, ‘that’s the voice, that’s the guitar—lose the guitar.’ And he did that, so it has great uses. We were able to take John’s voice and get it pure through this AI, so then we could mix the record as you would normally do.”

But as the media ran with the story, the use of AI in producing the final track has muddied the waters a bit. Now the legendary singer is taking to Twitter to help clarify what is and isn’t happening.

“Been great to see such an exciting response to our forthcoming Beatles project. No one is more excited than us to be sharing something with you later in the year,” he begins. “We’ve seen some confusion and speculation about it. Seems to be a lot of guesswork out there. Can’t say too much at this stage but to be clear, nothing has been artificially or synthetically created. It’s all real and we all play on it. We cleaned up some existing recordings—a process that has gone on for years. We hope you love it as much as we do. More news in due course.”
