In 1968 John married Yoko Ono and Sean was born in 1975. He, too, was only five when he lost his father but in an even more devastating way.
Julian has spoken angrily about how he was neglected by his father throughout his youth but during the new interview he is able to talk about their improved relationship in John’s final years.
He said: “Dad and I had been getting on and speaking a lot more on the phone, you know, when I was sort of 15, 16 and 17…
“I just remember that as being the last kind of moments (I spent with him), listening to him being extremely happy in a happy place, and doing what he loved, and the music that he played me at that particular point, Starting Over, and some of the other album tracks.
“I was very happy for him and looking forward to seeing him again. Anyway, in another dimension…”
He also open up about his admiration for his father’s final work, including the song Mother (below).
