AI-generated music is a bourgeoning and fraught topic, with artists either vocally opposing even the faintest hint of it, or some (like Grimes) more or less embracing it completely. Now, Paul McCartney seems to be on the ‘pro’ train, at least in part, since he has created a “new” Beatles song using AI and will be releasing it to the public later this year.

The song includes John Lennon vocals, pulled from an old demo recording, and the BBC report that first revealed the news says it’s probably from ‘Now and Then,’ a 1978 Lennon recording which was recorded to cassette from Lennon’s living room in NYC just before his death. The inspiration from the song came from Peter Jackson’s documentary ‘Get Back,’ McCartney told the BBC, since for that process a custom AI system was used to separate the vocals of the various Beatles members from background noise, enabling high-quality reproduction.
