Question: What secondary school was attended by the backing vocal singer on You're So Vain?

full_context: Document 1: 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 2: You're So Vain: ``You're So Vain ''is a song written in 1971 by Carly Simon and released in November 1972. The song is a critical profile of a self - absorbed lover about whom Simon asserts`` You're so vain, you probably think this song is about you.'' The title subject's identity has long been a matter of speculation, with Simon stating that the song refers to three men, only one of whom she has named publicly, actor Warren Beatty. The song is ranked at # 92 on Billboard's Greatest Songs of All - Time. ``You're So Vain ''was voted # 216 in RIAA's Songs of the Century, and in August 2014, the UK's Official Charts Company crowned it the ultimate song of the 1970s.
Document 3: Angie (song): The song is credited, as most Rolling Stones songs are, to both Mick Jagger and Keith Richards, but it is acknowledged to be almost completely written by Richards. "Angie" was recorded in November and December 1972 and is an acoustic-guitar-driven ballad characterizing the end of a romance. The song's distinctive piano accompaniment, written by Richards, was played on the album by Nicky Hopkins, a Rolling Stones recording-session regular. The strings on the piece (as well as on another song, "Winter") were arranged by Nicky Harrison. An unusual feature of the original recording is that singer Mick Jagger's vocal guide track (made before the final vocals were performed) is faintly audible throughout the song (an effect sometimes called a "ghost vocal").
Document 4: Jeff Rackley: Born in Nelson, Rackley attended Nelson College from 1966 to 1971. He was a member of the school's 1st XI cricket team from 1968 to 1970, captaining the side in 1970. He was also a member and captain of the 1st XV rugby team in 1970 and 1971.
Document 5: Kenny G: Kenny G attended Whitworth Elementary School, Sharples Junior High School, Franklin High School, and the University of Washington, all in his home city of Seattle. When he entered high school he failed at his first attempt to get into the jazz band but tried again the following year and earned first chair. His Franklin High School classmate Robert Damper (piano, keyboards) plays in his band. In addition to his studies while in high school, he took private lessons on the saxophone and clarinet from Johnny Jessen, once a week for a year.
Document 6: You're So Vain: The distinctive bass guitar intro is played by Klaus Voormann and the strings were arranged by Simon and orchestrated by Paul Buckmaster. Simon plays piano on the track.
Document 7: The Rolling Stones: The Rolling Stones are an English rock band formed in London, England in 1962. The first stable line - up consisted of Brian Jones (guitar, harmonica), Mick Jagger (lead vocals), Keith Richards (guitar, backing vocals), Bill Wyman (bass), Charlie Watts (drums), and Ian Stewart (piano). Stewart was removed from the official line - up in 1963 but continued as a touring member until his death in 1985. Jones left the band less than a month prior to his death in 1969, having already been replaced by Mick Taylor, who remained until 1974. After Taylor left the band, Ronnie Wood took his place in 1975 and has been on guitar in tandem with Richards ever since. Following Wyman's departure in 1993, Darryl Jones joined as their touring bassist. Touring keyboardists for the band have been Nicky Hopkins (1967 -- 1982), Ian McLagan (1978 -- 1981), Billy Preston (through the mid-1970s) and Chuck Leavell (1982 -- present). The band was first led by Brian Jones, but after teaming as the band's songwriters, Jagger and Richards assumed leadership while Jones dealt with legal and personal troubles.
Document 8: You're So Vain: In 1983, she said it is not about Mick Jagger, who contributed uncredited backing vocals to the song. In a 1993 book, Angie Bowie claimed to be the ``wife of a close friend ''mentioned in`` You're So Vain'', and that Jagger, for a time, had been ``obsessed ''with her. Simon made another comment about the subject's identity as a guest artist on Janet Jackson's 2001 single,`` Son of a Gun (I Betcha Think This Song Is About You)'', which sampled ``You're So Vain ''. Simon said about the song,`` The apricot scarf was worn by Nick (Delbanco). Nothing in the words referred to Mick.''
Document 9: Look What You Made Me Do: However, Maura Johnston of The Guardian wrote a negative review of the song, faulting the ``sloppy ''lyrics and blaming Swift for not giving a clear context in the lyrics. Brittany Spanos of Rolling Stone believed that the song marked a continuation of the feud between Swift and rapper Kanye West; the latter had previously name - dropped Swift in his song`` Famous'' by using the line, ``I feel like me and Taylor might still have sex / Why? / I made that bitch famous ''. The single was noted as being a darker, angrier work than what Swift had done before. Hugh McIntye of Forbes was critical of the change in style, saying that it`` did n't sound like (Swift)'' and that it ``may have some kinks to work out ''. Meaghan Garvey from Pitchfork referred to it in a review as`` a hardcore self - own'' track.
Document 10: The Rolling Stones: The Rolling Stones are an English rock band formed in London, England in 1962. The first stable line - up consisted of Brian Jones (guitar, harmonica), Mick Jagger (lead vocals), Keith Richards (guitar, backing vocals), Bill Wyman (bass), Charlie Watts (drums), and Ian Stewart (piano).

The band was first led by Brian Jones, but after developing into the band's songwriters, Jagger and Richards assumed leadership when Jones was dealing with personal troubles and legal issues.
Document 11: Don't Matter to Me: The song contains posthumous vocals from Michael Jackson, taken from part of an unreleased 1983 session between Jackson and Canadian singer - songwriter Paul Anka. ``Love Never Felt So Good '', released on Xscape, and`` This Is It'', also came from the same session; Anka is therefore credited as a songwriter on all three songs.
Document 12: Waiting on a Friend: The song is noted for its dreamy qualities brought on by the soft guitars, smooth rhythm, and Jagger's lilting refrain of ``doo - doo - doo '''s. Stones - recording veteran Nicky Hopkins performs the track's running piano. The Stones hired jazz saxophonist Sonny Rollins to perform the solo on this song, as well as two others on the album. On his addition to the track, Jagger said in 1985:
Document 13: Robert John Godfrey: Born on the Leeds Castle estate in Kent, England, Godfrey was educated at Finchden Manor in Tenterden, which was described by its founder George Lyward as a "therapeutic community for adolescents", other alumni of which included Alexis Korner and Tom Robinson. Although he didn't start to play the piano until the age of twelve, Godfrey's talent was prodigious enough to gain him admission to the Royal College of Music, then the Royal Academy of Music. He studied under concert pianist Malcolm Binns, and those around him included Sir Michael Tippett, Benjamin Britten and Hans Werner Henze.

Document 15: Mick Jagger: In September 1950, Keith Richards and Jagger were classmates at Wentworth Primary School, Dartford. In 1954, Jagger moved to Wilmington, Kent with his family. The same year he passed the eleven-plus and went to Dartford Grammar School, which now has the Mick Jagger Centre, named after its most famous alumnus, installed within the school's site. Jagger and Richards lost contact with each other when they went to different schools, but after a chance encounter on platform two at Dartford railway station in July 1960, resumed their friendship and discovered their shared love of rhythm and blues, which for Jagger had begun with Little Richard.
