Which singer performed "Your Song" at Prince William's wedding reception?

Elena Jane Goulding (born 30 December 1986) is an English singer and songwriter. Her career began when she met record producers Starsmith and Frankmusik, and she was later spotted by Jamie Lillywhite, who later became her manager and A&R. After signing to Polydor Records in July 2009, Goulding released her debut extended play, "An Introduction to Ellie Goulding later that year".

In 2010, she became the second artist to top the BBC's annual Sound of... poll and win the Critics' Choice Award at the Brit Awards in the same year. She released her debut studio album, "Lights", in 2010; it debuted at No. 1 on the UK Albums Chart and has sold over 850,000 copies in the United Kingdom. In November 2010, the album was reissued as "Bright Lights", which spawned two singles: a cover of Elton John's "Your Song" which was selected for the first John Lewis Christmas advert, reached No. 2 on the UK Singles Chart, and "Lights", which became Goulding's highest-charting single on the US Billboard Hot 100 to date, peaking at No. 2.

Goulding performed at the wedding reception of Prince William and Kate Middleton on 29 April 2011, and performed what she recalled as "about 14 songs", including her cover of "Your Song".
