George Harrison,MBE (25 February 1943 – 29 November 2001) was an English musician and singer-songwriter who achieved international fame as lead guitarist of The Beatles. Often referred to as "the quiet Beatle", Harrison became over time an admirer of Indian culture and mysticism, and introduced it to the other Beatles, as well as their Western audience. Following the band's break-up he was a successful solo artist, and later a founding member of the Traveling Wilburys. Harrison was also a session musician and a film and record producer. He is listed at number 11 in Rolling Stone magazine's list of "100 Greatest Guitarists of All Time".

Although most of The Beatles' songs were written by Lennon and McCartney, Beatle albums generally included one or two of Harrison's own songs, from With The Beatles onwards. His later compositions with The Beatles include "Here Comes the Sun", "Something" and "While My Guitar Gently Weeps". By the time of the band's break-up, Harrison had accumulated a backlog of material, which he then released as the triple album All Things Must Pass in 1970, from which two hit singles originated: a double A-side single, "My Sweet Lord" backed with "Isn't It a Pity", and "What Is Life". In addition to his solo work, Harrison co-wrote two hits for former Beatle Ringo Starr, as well as songs for the Traveling Wilburys—the supergroup he formed in 1988 with Jeff Lynne, Bob Dylan, Tom Petty, and Roy Orbison.
