A few weeks ago, I jokingly asked ChatGPT to write a "new" Beatles song and here's what it came up with. 

But now someone has taken this challenge one step farther. They recreated a solo Paul McCartney tune from 2013 and added in A.I generated John Lennon vocals, impossible since the late Beatle had already passed on in 1980. It's eerily close to the real thing. 

Then there's the solo John Lennon song that adds a McCartney contribution that also never took place. It, too, is a bit too close for comfort. 

Not sure if this is a good thing, but you have to admire how well it turned out. 

You can read about how this was done and hear both songs here.
