The Beatles’ AI-assisted track “Now and Then” won the Grammy for Best Rock Performance on Sunday night, marking the first time a song of its kind has taken home the award.

However, it’s essential to note that Paul McCartney did not utilize AI to create a LennonGPT bot. Instead, he employed noise reduction systems to clean up a decades-old, low-quality piano demo from his late bandmate. This technology is comparable to what video call providers like Zoom, FaceTime, and Google Meet use to block out unwanted background noise and deliver a clearer sound.

The surviving Beatles initially attempted to fix up Lennon’s demo in the 1990s, but the technology available at the time couldn’t quite extract Lennon’s muffled vocals. In 2022, after learning about the audio isolation techniques used by the filmmakers behind the archival Beatles documentary “Get Back,” they revisited “Now and Then.”
