Decades later, Julian Lennon confessed to CBS during the opening of his photographic exhibition, which marked the first time all the Lennon family — Yoko Ono included — were fully united, that he initially did feel abandoned by how John Lennon raised Sean: "When I saw the fact that, you know, he'd basically given up music for a couple of years to look after Sean, you know, that was — it was hurtful. I thought, 'Well, why didn't he do that for me?'" However, the two were close enough for Julian to join Sean as a surprise on-tour manager for two weeks in 2007.
A sibling friendship must have kindled, because Julian made peace with Yoko Ono. Later in the same CBS interview, Julian Lennon explained that his relationship with his brother was more important to him than his animosity with his brother's mother: "If I hurt Sean's mother then I hurt Sean. It's a roundabout way of thinking about things but because I love Sean so much I just don't want to hurt him."
In the same night, Sean Lennon paid a compliment back to his older half-brother: "Julian is the reason I started playing music, actually. Because when I was a kid I remember when his record came out. And he was, you know, the biggest thing that existed in the world... Actually he taught me how to play guitar. I remember him teaching me the song, 'Faith' by George Michael."
To which, an embarrassed Julian Lennon responded "Oh jeez."
