"A Moment Like This" is a song originally recorded by American singer Kelly Clarkson the first winner of American Idol, released as her debut single (as a double-A side single with "Before Your Love") which topped the Billboard Hot 100. In December 2006, the song was recorded by Leona Lewis, the winner of series 3 of The X Factor. The single was rush-released on Wednesday, December 20, 2006. This is unusual as most new singles are released on a Monday to gain maximum sales for the UK Singles Chart the following Sunday. The late release of "A Moment Like This" was because Lewis was only chosen as the artist on the night of Saturday, December 16, when the live final was transmitted. The song was available for download after she was announced winner of The X Factor. In January 2007, "A Moment Like This" was shortlisted for the British Single award at the 2007 BRIT Awards. It made it to the second round but was eliminated and did not make it to the final selection. In May it was awarded the prestigious Ivor Novello Award for Best Selling British Single. (wiki)
