Sean Ono Lennon, born on October 9, 1975—his father's 35th birthday—is a British-American musician and the son of John Lennon and Yoko Ono. His career spans performing, songwriting, and producing: he joined bands like Cibo Matto and the Plastic Ono Band, released solo albums such as Into the Sun (1998) and Asterisms (2024), and served as executive producer for the 2024 documentary One to One: John & Yoko. His early life was marked by both tragedy and unique moments—his father was murdered when he was just five, yet he later received one of the first Macintosh computers from Steve Jobs at his ninth birthday party in 1984. He began collaborating with his mother as a child and co-wrote a song with Lenny Kravitz at age 16, before dropping out of Columbia University to focus on music. Today, he holds dual US/UK citizenship and continues to honor his parents' legacy through his diverse musical projects.
