Sir Paul McCartney looked dapper in a blue striped blazer as he left Cecconi’s restaurant in London’s Mayfair on Wednesday. 

The Beatles musician, 80, looked in high spirits as he stepped out and with friends after his lunch date. 

The legendary British songwriter dressed in a navy open collar shirt, which he teamed with a pair of dark trousers. 

Sir Paul kept comfortable by rocking a pair of black trainers and shielded from the sun behind a pair of dark sunglasses. 

He sported a salt and pepper stubble and left his long locks pushed over to one side.

The musician’s appearance comes after the ground-breaking news that he is using artificial intelligence (AI) to ‘extricate’ John Lennon’s voice from an old demo to create the ‘final Beatles record.’

While he’s yet to name the song, it’s likely to be a 1978 Lennon composition called Now And Then, according to the BBC.

Speaking to Radio 4’s Today programme, McCartney explained: ‘We just finished it up and it’ll be released this year.’

Now And Then was one of several songs recorded by Lennon shortly before his death in 1980.

Two of the other tracks – Free As A Bird and Real Love – were cleaned up by producer Jeff Lynne before being released in 1995 and 1996.

But he struggled to clean up Now And Then, and his attempt was deemed ‘rubbish’ by George Harrison, who refused to work on it.

However, AI technology has given McCartney a new way to revive the song once more.

Speaking to Radio 4’s Martha Kearney, McCartney explained how he turned to director, Peter Jackson, who had used AI to create ‘clean’ audio in the Get Back documentary.

‘He [Jackson] was able to extricate John’s voice from a ropey little bit of cassette,’ he explained.

‘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”.

‘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.’

It remains unclear when this year McCartney plans to release the ‘final Beatles record’.

The Beatles aren’t the only band using AI to complete unfinished songs.

Paul’s new book, titled 1964: Eyes of the Storm, Photographs and Reflections by Paul McCartney, is published from 13 June 2023 via Penguin Press.

The exhibition, Paul McCartney Photographs 1963-64: Eyes of the Storm, at the National Portrait Gallery, London, will run from June 28 until October 1.
