He was born John Winston Lennon.

After his estrangement from Yoko, John began a relationship with May Pang, Yoko's personal assistant. The pair soon moved to California, beginning an 18-month period John would later call his "lost weekend".

"Strawberry Fields Forever" is one of the defining works of the psychedelic rock genre and was considered by John to be his greatest accomplishment. The track incorporates reverse-recorded instrumentation and tape loops, and was created from the editing together of two separate versions of the song--each one entirely different in tempo, mood and musical key.

Although Cynthia was originally frightened by John's attitude and appearance, when she learned that he was obsessed with French actress Brigitte Bardot, she dyed her hair blonde to get his attention. They were married on August 23, 1962.

Ono became pregnant in 1968 and miscarried a male child they named John Ono Lennon II on 21 November 1968.

The song was written as an attack on former Beatles bandmate and songwriting partner, Paul McCartney. Ringo Starr visited the studio during the recording of the song and was reportedly upset, saying: "That's enough, John."

The Quarrymen were a British skiffle group, formed by John in Liverpool in 1956, which eventually evolved into the Beatles. Skiffle was a relatively obscure genre, and it might have been largely forgotten if not for its revival in the United Kingdom in the 1950s and the success of its main proponent, Lonnie Donegan.

John was born and raised in Liverpool.

After he married Yoko in 1969, he added "Ono" as a second middle name.

John moved to Manhattan in 1971, where his criticism of the Vietnam War resulted in a lengthy attempt by Richard Nixon's administration to deport him.
