Billy & Emily England, Semi-Finals 1
Residents of the U.K., brother-and-sister duo Billy and Emily England won over Simon's vote with their outstanding roller-skating routine. The duo had previously auditioned for "Britain's Got Talent," and Cowell remembered their impressive routine. The duo has been skating since they were kids; their mother bought their first pair of roller skates and their passion grew year by year. They practiced every day - even on the kitchen table - and began to perform at school and in churches around England. As they perfected their skills, local TV stations and newspapers began to notice and they soon became local stars.
