John Winston Ono Lennon, MBE was an English singer and songwriter who rose to worldwide fame as a co-founder of the band the Beatles, the most commercially successful band in the history of popular music. With fellow member Paul McCartney, he formed a celebrated songwriting partnership. Born and raised in Liverpool, Lennon became involved in the skiffle craze as a teenager; his first band, the Quarrymen, evolved into the Beatles in 1960. When the group disbanded in 1970, Lennon embarked on a solo career that produced the critically acclaimed albums John Lennon/Plastic Ono Band and Imagine, and iconic songs such as "Give Peace a Chance", "Working Class Hero", and "Imagine".
