Question: Which American singer-songwriter lip-synched lyrics for Elton John?
Context: Elton John is the second studio album by English singer-songwriter Elton John, released on 10 April 1970 by DJM Records.  It was released by Uni Records as John's debut album in the United States; many people there assumed it was his first album, as "Empty Sky" was not released in that country until 1975.  "Elton John" includes his breakthrough single "Your Song", and helped to establish his career during what was considered the "singer-songwriter" era of popular music.  In the US, it was certified gold in February 1971 by the Recording Industry Association of America (RIAA).  In the same year, it was nominated for the Grammy Award for Album of the Year. Elton John: Me, Myself & I is a 2007 documentary filmed after the death of Elton John's good friend Diana and other soul shaking events that caused him to reassess his life.  It is a candid appraisal by Elton John (tongue in cheek) of his fame, drug use, sexuality, and mistakenly taking his life for granted.  It was filmed in Las Vegas, Nevada, United States Justin Randall Timberlake (born January 31, 1981) is an American singer-songwriter, actor and record producer.  Born and raised in Tennessee, he appeared on the television shows "Star Search" and "The All-New Mickey Mouse Club" as a child.  In the late 1990s, Timberlake rose to prominence as one of the two lead vocalists and youngest member of NSYNC, which eventually became one of the best-selling boy bands of all time.  Timberlake began to adopt a more mature image as an artist with the release of his debut solo album, the R&B-focused "Justified" (2002), which yielded the successful singles "Cry Me a River" and "Rock Your Body", and earned his first two Grammy Awards. Elton John: The Classic Years (known in North America as Elton John: The Remasters) was a remastering series of Sir Elton John's albums, in which some of the albums included bonus tracks. "The Goaldiggers Song" is a charity single by Elton John, released in 1977.  The song is written for the Goaldigger's charity to provide playing fields in under-privileged areas.  At the time in 1977, Elton John was living reclused in London; the only time he would go out was to go see his football team Watford F.C. play.  The single never charted anywhere, as it was a limited charity release-only 500 copies were pressed, approximately half of which were signed by Elton.  It was available for a cost of five UK pounds by mail-order only and featured Elton and a number of other British celebrities including Jimmy Hill and Eric Morecombe in conversation on the B-side.  The tapes were destroyed after the pressing, so no other official copies of the recording exist. Elton John’s Greatest Hits Volume III is the twenty-seventh album release for Elton John.  Released in 1987, 10 years after "Elton John's Greatest Hits Volume II", the compilation album features his greatest hits from 1979–1986 and was made available only in the United States and Canada.  All of the songs featured had previously been released on a previous album. The videography of Elton John consists of 118 music videos and 17 video albums.  Since 1970, John has continually released promotional music videos, beginning with "Your Song" and only sporadically releasing videos thereafter.  It was not until "Visions" in 1981, a release that included music videos of every song from his album "The Fox", as well as the rise of MTV, that he began to release videos more frequently.  He had usually appeared in his music videos, but after 2001, John began appearing less and less in his own videos, sometimes opting to have other actors, such famous names as Justin Timberlake and Robert Downey, Jr., lip-synch the lyrics. Raymond Thomas "Ray" Cooper (born 19 September 1947) is an English virtuoso percussionist.  He is a session and road-tour percussionist, and occasional actor, who has worked with several musically diverse bands and artists including George Harrison, Billy Joel, Rick Wakeman, Eric Clapton, Pink Floyd and Elton John.  Cooper absorbed the influence of rock drummers from the 1960s and 1970s such as Ginger Baker, Carmine Appice, and John Bonham.  Incorporation of unusual instruments (for rock drummers of the time) such as cowbells, glockenspiel, and tubular bells, along with several standard kit elements, helped create a highly varied setup.  Continually modified to this day, Cooper's percussion set offers an enormous array of percussion instruments for sonic diversity such as the tambourine, congas, crash cymbals, cowbells, roto toms, tubular bells, the gong, snare and timpani.  For two decades Cooper honed his technique; In the 1990s, he reinvented his style.  He is known for the 7-minute percussion and drum solos he performed during the years 1990–1991 for Eric Clapton and for the 7-minute percussion and drum solos during all the 1994 Face to Face Tours with Billy Joel, and Elton John, and the tours with the Elton John band during the years of 1994–1995. "Mona Lisas and Mad Hatters" is a song from the Elton John album "Honky Château".  The lyrics were written by Bernie Taupin and is his take on New York City after hearing a gun go off near his hotel window during his first visit to the city.  The song's lyrics were partly inspired by Ben E. King's "Spanish Harlem," written by Jerry Leiber and Phil Spector, in which he sings "There is a rose in Spanish Harlem."  In response to this, Taupin writes, Allmusic critic Stewart Mason noted that the song is "less saccharine than many similar Elton John and Bernie Taupin ballads" and praised the "somewhat uncharacteristic emotional directness" of its lyrics.  It was released as the B-side of the "Harmony" U.K. single in 1980. "Circle of Life" is a song from Disney's 1994 animated film "The Lion King".  Composed by Elton John, with lyrics by Tim Rice, the song was performed by Carmen Twillie (the deep female lead vocals) and Lebo M. (opening Zulu vocals) as the film's opening song.  In an interview, Rice said he was amazed at the speed with which John composed: "I gave him the lyrics at the beginning of the session at about two in the afternoon.  By half-past three, he'd finished writing and recording a stunning demo."  Elton John sang a pop version (with alternative lyrics) of the song with the London Community Gospel Choir, which was included in the film's soundtrack and made into a music video.  "Circle of Life" was nominated for the Academy Award for Best Song in 1994, along with two other songs from "The Lion King": "Hakuna Matata" and "Can You Feel the Love Tonight" which won the award.
