The Beatles may have one last hit song in them yet – despite being without frontman John Lennon for more than 40 years.

The Beatles may have one last hit song in them yet – despite being without frontman John Lennon for more than 40 years.

It’s all thanks to artificial intelligence (AI), reports The Sun.

Sir Paul McCartney, who played bass guitar as well as writing songs and sharing lead vocals with Lennon, made the shock announcement on BBC Radio 4’s Today program.

The music legend explained that AI technology had been used to “extricate” Lennon’s voice from a “ropey” old demo so that the song could be completed.

“We just finished it up and it’ll be released this year,” he said.

Lennon had left a demo tape titled “For Paul” shortly before his untimely death in 1980, with a trio of songs on it.

“We had John’s voice and a piano and he could separate them with AI. They tell the machine, ‘That’s the voice. This is a guitar. Lose the guitar’,” McCartney told Radio 4.

“So when we came to make what will be the last Beatles’ record, it was a demo that John had [and] we were able to take John’s voice and get it pure through this AI.

“Then we can mix the record, as you would normally do. So it gives you some sort of leeway.”
