Short answers, pulled from the story.
Julian Lennon inspired three Beatles songs: "Lucy in the Sky with Diamonds" (1967), whose lyrics were based on a watercolour he painted of his nursery school friend Lucy O'Donnell; "Hey Jude" (1968), written by Paul McCartney to console him over his parents' divorce; and "Good Night" (1968), a lullaby that closed The White Album.
Julian Lennon's debut album was Valotte, released in 1984 and produced by Phil Ramone. It produced two top-10 hits and earned Lennon a Grammy nomination for Best New Artist in 1986.
The White Feather Foundation is a philanthropic organisation Julian Lennon founded in 2007, named after a symbol of peace his father had told him would signal that everything would be all right. Its mission focuses on clean water, the preservation of Indigenous cultures, education and health, and the environment. In 2008, Prince Albert II of Monaco presented it with the Better World Environmental Award.
Julian Lennon had a largely absent and difficult relationship with his father. After his parents' divorce in 1968, he had almost no contact with John until the early 1970s. He later described his father as a hypocrite for preaching peace and love while neglecting his family. John excluded Julian from his will, but Julian reached a settlement with his father's estate in 1996, reportedly worth £20 million.
Julian Lennon named his 2022 album Jude as a reference to the Beatles song "Hey Jude", which Paul McCartney wrote in 1968 to give Julian hope following his parents' divorce. Lennon described the title as "very coming of age" and a way of facing up to who he is. McCartney provided a handwritten "Jude" motif for the album's artwork.
Julian Lennon produced Whaledreamers, about the Mirning people of Australia and their connection with whales, which was shown at the 2007 Cannes Film Festival and won eight international awards. He was also executive producer of Kiss the Ground (2020), a documentary about regenerative agriculture narrated by Woody Harrelson, and Women of the White Buffalo (2022), which chronicles the lives of women on the Lakota Pine Ridge Indian Reservation.
