Background: "Layla" is a song written by Eric Clapton and Jim Gordon, originally released by their blues rock band Derek and the Dominos, as the thirteenth track from their album Layla and Other Assorted Love Songs (November 1970). Its famously contrasting movements were composed separately by Clapton and Gordon. The song was inspired by a love story that originated in 7th-century Arabia and later formed the basis of The Story of Layla and Majnun by the 12th-century Persian poet Nizami Ganjavi, a copy of which Ian Dallas had given to Clapton. The book moved Clapton profoundly, because it was the tale of a young man who fell hopelessly in love with a beautiful, young girl and went crazy and so could not marry her.
Context: The album Layla and Other Assorted Love Songs opened to lacklustre sales as the album never actually reached the music charts in the United Kingdom, possibly in part because Clapton's name was found only on the back cover. In addition, the song's length proved prohibitive for radio airplay. As a result, an edited version of the song, trimmed to 2:43, was released as a single in March 1971 by Atco Records in the United States. The version peaked at #51 on the Billboard Hot 100 singles chart. When "Layla" was re-released on the 1972 compilations The History of Eric Clapton and Duane Allman's An Anthology and then released the full 7:10 version as a single, it charted at number seven in the United Kingdom and reached number 10 in the United States. With good sales figures, the Billboard magazine was able to rank the Rock single as the 60th best-selling song in 1972. In 1982, "Layla" was re-released as a single in the United Kingdom, and peaked at number four. This time the whole seven-minute single charted, containing the trailing two-thirds which is instrumental only. Critical opinion since has been overwhelmingly positive. Dave Marsh, in The Rolling Stone Illustrated History of Rock and Roll, wrote that "there are few moments in the repertoire of recorded rock where a singer or writer has reached so deeply into himself that the effect of hearing them is akin to witnessing a murder or a suicide... to me 'Layla' is the greatest of them." Marsh listed "Layla" at number 156 in his The Heart of Rock & Soul: The 1001 Greatest Singles Ever Made. In May 1980, "Layla" was covered by the London Symphony Orchestra, but without the lyrics, being recorded at EMI Studio One, Abbey Road, London. A similar version has been performed by the Royal Philharmonic Orchestra. On 20 September 1983, a benefit show called the ARMS Charity Concert for Multiple Sclerosis at the Royal Albert Hall in London featured a jam with Eric Clapton, Jeff Beck, and Jimmy Page performing "Layla". Clapton, Beck, and Page were the Yardbirds' successive lead guitarists from 1963 to 1968. In 2003, the Allman Brothers Band began playing the song in concert. Warren Haynes sang the vocal, Gregg Allman played the piano part, and Derek Trucks played Duane Allman's guitar parts during the coda. The performances were seen as a tribute not only to Allman, but also to producer Tom Dowd, who had died the previous year. Eric Clapton recorded yet a third version. "Layla" appears as track seven on Play the Blues: Live from Jazz at Lincoln Center. Personnel on this version include Wynton Marsalis (vocals, trumpet), Eric Clapton (vocals, guitar), Victor Goines (clarinet), Marcus Printup (trumpet), Chris Crenshaw (trombone, vocals), Don Vappie (banjo), Chris Stainton (keyboards), Dan Nimmer (piano), Carlos Henriquez (bass), and Ali Jackson (drums).
