Sean Taro Ono Lennon is a British-American musician, songwriter, producer and multi-instrumentalist. He is the son of John Lennon and Yoko Ono, and half-brother to Julian Lennon. Over the course of his career, he has been a member of the bands Cibo Matto, The Ghost of a Saber Tooth Tiger, The Claypool Lennon Delirium and his parents’ group Plastic Ono Band.
To me that means he loses his ‘stranger’ classification.
You ‘know’ him because he is a musician, or because he has famous parents? I don’t ‘know’ Sean Lennon... I know of him.
