John Charles Julian Lennon (born 8 April 1963) is an English musician and photographer, son of The Beatles member John Lennon and his first wife Cynthia.

He was the direct inspiration for three Beatles’ songs: “Lucy in the Sky with Diamonds” (1967), “Hey Jude” (1968), and “Good Night” (1968). His parents divorced in 1968, and he is half-brother to Sean Lennon. He has produced a number of albums starting with Valotte (1984), as well as a documentary film WhaleDreamers on an environmental theme. Lennon has also held exhibitions of his photography.

Lennon inspired one of his father’s most famous songs, “Lucy in the Sky with Diamonds,” whose lyrics describe a picture the boy had drawn, a watercolor painting of his friend, Lucy O’Donnell, from nursery school, surrounded by stars. Another composition of his father inspired by him was the lullaby “Good Night“, the closing song of The Beatles (also known as The White Album). In 1967, he attended the set of the Beatles’ film Magical Mystery Tour.
