The two have spoken about their relationship multiple times over the years, with Julian sharing in 2023 that rumours of an alleged feud between them were “such bull” as they had “never had a fight in our life.” In 2025, Sean spoke out against any rumours of bad blood between them too , asking fans not to compare them as they are “best buddies”.

Julian has established himself as a musician, photographer, author, and philanthropist, and Sean has a successful solo career as well as joining forces with Primus’ Les Claypool once again to release their third album as the Claypool Lennon Delirium .

As well as his own musical endeavours, Sean has also been hands on with many Beatles projects over the years – including producing a remastered version of a 1995 documentary series called The Beatles Anthology last year, and also overseeing the production of a ‘Mind Games’ reissue boxset .

That’s how I look at it.” Also in that interview, Lennon provided an update on his mother, who has taken a step back from public life in recent years.

“She’s good… she’s 92, so she’s slowed down a lot, and she’s retired.

That’s why I’m kind of trying to do the work that she used to do,” he said.
