The evening's entertainment was a musical show based on the works of renowned musical director Sir Andrew Lloyd Webber. Hayley sang four songs; a duet of "Let Us Love and Peace" from A Beautiful Game with Irish singer Shonagh Daly, a solo of Pie Jesu, and a duet of I Believe My Heart, the lead track to Andrew Lloyd Webber's new musical "Woman in White" which she sang with the musical's male star, Kevin McKidd. For the evening's finale Hayley joined the other stars on stage for a stunning rendition of No Matter What.

On the evening Hayley commented: "It's been an amazing experience. It's such an honor to be asked to perform in front of the Queen of England and some of the world's leading political figures and equally amazing to work with Andrew Lloyd Webber. I still can't quite believe it."

In the short time since the release of Hayley Westenra's first international album PURE on Decca/Universal, the 16-year-old from Christchurch, New Zealand has made chart-busting history in the music industry by becoming the fastest-selling debut classical artist in U.K. history. PURE took one week to reach Gold status and has hit Platinum after only 8 weeks. ÊPURE will be released in the US on April 6.

Hayley's forthcoming schedule includes a concert with Jose Carreras at the Royal Albert Hall in London, performing at the Royal Variety Show alongside Pavarotti in Edinburgh and leading the Amnesty International Christmas concert in London's Trafalgar square. In 2004 Hayley will be touring New Zealand, Australia and the UK; releasing PURE in North America and Europe; sitting her GCSE exams in London; and making time to further develop her role as the youngest ever ambassador of UNICEF.
