Question: How high did the single from Elton John's Christmas Party peak on the UK Singles Charts?
Context: The discography of Gnarls Barkley, an American alternative hip hop duo composed of record producer Danger Mouse and soul singer Cee Lo Green, consists of two studio albums, two extended plays, seven singles and seven music videos.  The duo originally met in the late 1990s, and began to record music together in 2003 following the release of Danger Mouse's 2003 album "Ghetto Pop Life".  Their first single, "Crazy", was released in 2006; it achieved worldwide chart success, reaching number two on the US "Billboard" Hot 100 – where it was certified double platinum by the Recording Industry Association of America (RIAA) – and reaching the top ten of the Australian, New Zealand and Swiss singles charts, among others.  It also topped the UK Singles Chart, attracting considerable attention for becoming the first song ever to top the chart on digital download sales alone, following a change to the chart's eligibility rules allowing songs to chart purely on digital sales providing that it was given a physical release the following week.  The song appeared on Gnarls Barkley's debut studio album, "St. Elsewhere", which peaked at number four on the US "Billboard" 200 as well as topping the New Zealand and United Kingdom albums charts.  Three further singles – "Smiley Faces", which reached the top ten of the UK and Irish singles charts, "Who Cares? " and a cover of the Violent Femmes song "Gone Daddy Gone" – were released from "St. Elsewhere", although none of them appeared on the "Billboard" Hot 100. The columns Song, Album, and Year list each song title, the official release on which the song first appeared, and the year in which the song was released for the first time.  The columns Length, Author, and Producer indicate the length of the track, the author of the song (most often Wainwright alone), and the producer of the track.  References are also provided for each song in the last column of the table.  While many songs listed appear on multiple releases (for example, "Spotlight on Christmas" appears on "Maybe This Christmas Too? ", "The McGarrigle Christmas Hour", and "Elton John's Christmas Party"), songs are listed based on the first release and only appear twice when the recordings have different production information (producer, length, etc.). "Silver Machine" is a 1972 song by the UK rock group Hawkwind.  It was originally released as a single on 9 June 1972, reaching number three on the UK singles chart.  The single was re-issued in 1976, again in 1978 reaching number 34 on the UK singles charts, and once again in 1983 reaching number 67 on the UK singles charts.  The original mix has been re-released on the remasters version of "In Search of Space". Elton John's Christmas Party is a Christmas-themed compilation album from British singer-songwriter Elton John.  It features his 1973 Christmas single, "Step into Christmas", and a new duet with Joss Stone, "Calling It Christmas".  According to John's introduction in the liner notes, as opposed to doing an album of his versions of already famous songs, he chose to do a compilation with some of his favorite holiday songs by other artists. "Don't Let the Sun Go Down on Me" is a song written by English singer Elton John and his lyricist Bernie Taupin.  It was originally recorded in 1974 by Elton John for his studio album "Caribou" and was released as a single that peaked at number two on the "Billboard" Hot 100 chart and reached number 16 on the UK Singles Chart.  The song found further success in 1991 in a live cover version recorded as a duet between John and George Michael, which reached number one in the UK and US. "Do They Know It's Christmas?"  is a song written in 1984 by Bob Geldof and Midge Ure in reaction to television reports of the 1983–85 famine in Ethiopia.  It was first recorded in a single day on 25 November 1984 by Band Aid, a supergroup put together by Geldof and Ure and consisting mainly of the biggest British and Irish musical acts at the time.  The single was released in the United Kingdom on 3 December 1984 and aided by considerable publicity it entered the UK Singles Chart at number one and stayed there for five weeks, becoming the Christmas number one of 1984.  The record became the fastest selling single in UK chart history, selling a million copies in the first week alone and passing 3 million on the last day of 1984, on the way to becoming the biggest selling single of all time in the UK.  It held this title until 1997 when it was overtaken by Elton John's "Candle in the Wind 1997", released in tribute to Princess Diana following her death.  The original version of "Do They Know It's Christmas?"  has sold 3.8 million copies in the UK to date. According to "Guinness World Records", "White Christmas" (1942) by Bing Crosby is the best-selling single worldwide, with estimated sales of over 50 million copies.  The song recognized as "the best-selling single of all time" was released before the pop/rock singles-chart era and "was listed as the world's best-selling single in the first-ever "Guinness Book of Records" (published in 1955) and—remarkably—still retains the title more than 50 years later."  "Guinness World Records" states that double A-side charity single "Candle in the Wind 1997"/"Something About the Way You Look Tonight" (1997) by Elton John, a tribute to the late Diana, Princess of Wales, is "the biggest-selling single since UK and US singles charts began in the 1950s, having accumulated worldwide sales of 33 million copies," making it the second-best-selling single of all time.
