Document 14: George Harrison: George Harrison, {'1': ", '2': ", '3': ", '4': "} (25 February 1943 – 29 November 2001) was an English guitarist, singer-songwriter, and producer who achieved international fame as the lead guitarist of the Beatles. Often referred to as "the quiet Beatle", Harrison embraced Hinduism and helped broaden the horizons of his fellow bandmates as well as their American audience by incorporating Indian instrumentation in their music. Although most of the Beatles' songs were written by John Lennon and Paul McCartney, most Beatles albums from 1965 onwards contained at least two Harrison compositions. His songs for the group included "Taxman", "Within You Without You", "While My Guitar Gently Weeps", "Here Comes the Sun" and "Something", the last of which became the Beatles' second-most covered song.
Document 15: Horse to the Water: "Horse to the Water" is a song written by George Harrison and his son Dhani. It was originally performed by Jools Holland's Rhythm and Blues Orchestra, featuring Harrison, on the album "Small World, Big Band" (also known as "Jools Holland's Big Band Rhythm & Blues"). Recorded on 2 October 2001, the song is Harrison's last performance on a record. Harrison only performed vocals on the track, as he was too weak from battling cancer to play guitar, and he died just over eight weeks later on 29 November. He listed the song's publisher as "R.I.P Music Ltd" instead of his usual music company Harrisongs, which Holland said showed "Harrison's dark sense of humour." (In the liner notes of some versions of the CD, the credit is "Umlaut Corporation.")
