When Katie Waissel walked onto the X Factor UK stage in 2010 she had one song in mind. Etta James' At Last. One of the most beloved and most powerful songs ever recorded. Then Simon Cowell told her to change it before she even sang a single note. So she tried. She attempted We Are The Champions by Queen instead. Then she forgot the words. And in that moment something completely unexpected happened. Simon allowed her to go back to her original song. Then Katie Waissel sang Etta James' At Last. And what came out of a young woman from London who had just forgotten the lyrics to an entirely different song was so completely extraordinary that two judges put her through to bootcamp before she even finished. Simon said change the song. She forgot the new one. Then Etta James changed everything. 0:00 Katie Waissel - X Factor UK 2010 S7 6:43 Katie Waissel (Boot Camp) - X Factor UK 2010 S7 8:49 Katie Waissel (Judges' Houses) - X Factor UK 2010 S7 11:50 Katie Waissel (Live Show) (Week 1) - X Fac...
