Ellie Goulding sang for Prince William and bride Kate Middleton at Buckingham PalaceEllie Goulding has described serenading the Duke and Duchess of Cambridge as a "very surreal, incredible experience" after being asked by the couple to perform at their wedding.
The singer-songwriter played to 650 guests at the after-dinner party hosted by the Queen and was honoured to sing for William and Kate's first dance.
Describing the poignant moment on the BBC's The One Show, the chart-topper said: "It was a very surreal, incredible experience. I'll never forget it. It was amazing."
Asked by presenter Alex Jones if she had been nervous, she said: "I get nervous quite a lot generally so yes, I was."
When Jones enquired if the Duke was "a good mover", Goulding dodged the question, replying: "It was a good night. Everyone was having fun."
Among several numbers performed by the singer, guests enjoyed her hit version of Your Song, a piece written by Sir Elton John, a close friend of William's late mother, the Princess of Wales.
The 24-year-old said that she could not remember how many songs she had played but added there were "quite a few".
The star said she could not believe it when she was asked to perform at the royal wedding after being introduced to William and Kate last year.
"I met them at a festival last year. Quite strangely I was introduced to them by Tinie Tempah who is also a friend of mine," Goulding said.
"It was very bizarre but that's when I met them and then I found out a while ago that they wanted me to sing."
Goulding, from Kington, Herefordshire, got her big break when she was tipped as the act to watch last year by industry experts in the BBC Sound of 2010 list.
