The story behind the song goes something like this. In 1966, George Harrison married Pattie Boyd, a model he met during the filming of A Hard Day's Night. During the late 1960s, Clapton and Harrison became good friends. Clapton contributed guitar work on Harrison's song "While My Guitar Gently Weeps" on The Beatles' White Album but remained uncredited, and Harrison played guitar pseudonymously on Cream's "Badge" from Goodbye. However, trouble was brewing for Clapton. Besides his difficulty in keeping a band together and his growing heroin addiction, when Boyd came to him for aid during marital troubles, Clapton fell desperately in love with her. The title, "Layla", was inspired by the Persian love story, The Story of Layla, by the Persian classical poet Nezami. When he wrote "Layla", Clapton had recently been given a copy of the story by a friend who was in the process of converting to Islam. Nezami's tale, about a moon-princess who was married off by her father to someone other than the man who was desperately in love with her, resulting in his madness, struck a deep chord with Clapton. Boyd divorced Harrison in 1977 and married Clapton in 1979. Harrison was not bitter about the divorce and attended Clapton's wedding with Ringo Starr and Paul McCartney. During their relationship, Clapton wrote another love ballad for her, "Wonderful Tonight." Clapton and Boyd divorced in 1989 after several years of separation.
