One time, he joked that he sounds more like John Lennon.
It is clear that Beatle Jim McCartney is his son.
With his long, bushy beard, the 44-year-old musician looked the image of his father Paul as he as he went shopping in London, braving the cold in sandals.
McCartney, brother to Mary (52), and Stella (50), is the only child of Sir Paul (79), and his widow Linda.
He has played on some of his father’s albums as well as releasing music of his own.

After largely shunning the limelight, even working as a waiter in Brighton, McCartney later followed in his father’s musical footsteps.
The first two and a half years of his life were spent touring the country with his parents, who toured together with Wings.
He later played guitar on Sir Paul’s records Flaming Pie and Driving Rain as well as The Light Comes From Within – a track he recorded with his mother before her death from breast cancer in 1998.
He released his debut single Available Light in 2010 before releasing his first album Me in 2013 and his second, The Blackberry Train, in 2016 – both co-produced by his father.
He previously said he had aims to be ‘better than the Beatles’.

‘When I got to a certain age, I realised that I was somewhat better than other kids at school at guitar and took pride and enjoyment in that,’ he told the BBC in 2012.
‘I then dreamt of being better than The Beatles. I’m not sure if I can do that. If anything, I would love to be equal to The Beatles – but even that’s quite tough.’
He also revealed he was considering forming a group featuring the offspring of the Fab Four, including Ringo Starr’s son Jason, 54, Lennon’s youngest son Sean, 46, and George Harrison’s only son, Dhani, 43.
