Paul McCartney wrote the Beatles' song for the youngster after John left the family home
Having one of the most famous songs of all time named after you clearly isn't all it's cracked up to be.
As the story goes, Paul McCartney originally wrote the song - which was first known as 'Hey Jules' - for John Lennon's 5-year-old son Julian, to comfort him after his parents' marriage had broken up and John had left his mother for Yoko Ono.
However, the sheer ubiquity of the Beatles' 1968 song has meant that it has dogged Julian Lennon throughout his life - and he's had enough of it.
He said in a new interview with Esquire: "It’s a beautiful sentiment, no question about that, and I’m very thankful – but I’ve also been driven up the wall by it.
"I love the fact that [McCartney] wrote a song about me and for Mum, but depending on what side of the bed one woke up on, and where you’re hearing it, it can be a good or a slightly frustrating thing."
He added that the song was a reminder of a very difficult and "dark" time for him and his mother Cynthia.
"The weird thing with the audience is they think it’s cute sometimes, quoting ‘Hey Jude’ to me, but I don’t think they realise there’s a lot of pain behind what happened,” he said. "Every time you quote that, it reminds me of my mother being separated from my father, the love that was lost, the fact that I rarely saw my father again ever... a lot of people don’t quite get how intense, how emotional, and how personal that is. It’s not just a ‘pick yourself up and dust yourself off and be happy’."
He added: "There’s deep emotional pain. I can celebrate it – but also it’s something that’ll always be dark to me."
Lennon was 17 years old when his father was shot and killed by Mark Chapman at the Dakota Building in New York, and says that he only saw him "maybe a couple of times" in the period between him leaving the family home and his death.
