Document 6: Eric Clapton: After being discharged, it was recommended by doctors of Hazelden that Clapton not partake in any activities that would act as triggers for his alcoholism or stress. A few months after his discharge, Clapton began working on his next album, against doctors' orders. Working with Tom Dowd, he produced what he thought as his "most forced" album to date, Money and Cigarettes. Clapton chose the name of the album "because that's all I saw myself having left" after his first rehabilitation from alcoholism.In 1984 he performed on former Pink Floyd member Roger Waters' solo album, The Pros and Cons of Hitch Hiking, and joined the supporting tour. Since then Waters and Clapton have had a close relationship. In 2005 they performed together for the Tsunami Relief Fund.

Kennedy Stadium in Philadelphia on 13 July 1985, playing with Phil Collins, Tim Renwick, Chris Stainton, Jamie Oldaker, Marcy Levy, Shaun Murphy, and Donald 'Duck' Dunn. When offered a slot close to peak viewing hours, he was apparently flattered.

Document 14: Eric Clapton: Clapton was born on 30 March 1945 in Ripley, Surrey, England, to 16-year-old Patricia Molly Clapton (7 January 1929 – March 1999) and Edward Walter Fryer (21 March 1920 – 15 May 1985), a 25-year-old soldier from Montreal, Quebec. Fryer shipped off to war prior to Clapton's birth and then returned to Canada. Clapton grew up believing that his grandmother, Rose, and her second husband, Jack Clapp, Patricia's stepfather, were his parents, and that his mother was actually his older sister. The similarity in surnames gave rise to the erroneous belief that Clapton's real surname is Clapp (Reginald Cecil Clapton was the name of Rose's first husband, Eric Clapton's maternal grandfather). Years later, his mother married another Canadian soldier and moved to Germany, leaving young Eric with his grandparents in Surrey.Clapton received an acoustic Hoyer guitar, made in Germany, for his thirteenth birthday, but the inexpensive steel-stringed instrument was difficult to play and he briefly lost interest. Two years later Clapton picked it up again and started playing consistently. Clapton was influenced by the blues from an early age, and practised long hours to learn the chords of blues music by playing along to the records. He preserved his practice sessions using his portable Grundig reel-to-reel tape recorder, listening to them over and over until he felt he'd got it right.In 1961, after leaving Hollyfield School in Surbiton, Clapton studied at the Kingston College of Art but was dismissed at the end of the academic year because his focus remained on music rather than art. His guitar playing was so advanced that, by the age of 16, he was getting noticed. Around this time, Clapton began busking around Kingston, Richmond, and the West End.
Document 15: Let It Down: "Let It Down" is a song by English musician George Harrison, released on his 1970 triple album "All Things Must Pass". The recording was co-produced by Phil Spector and employs the latter's Wall of Sound production technique to lavish effect. Its brash opening and choruses contrast with the ethereal quality of the verses – a loud/soft approach that has been credited with influencing indie bands during the 1980s and 1990s.
