Amber Riley and her Glee castmates give a performance of their version of the classic Journey song “Don’t Stop Believin’” on UK’s The X Factor on Sunday (December 5).  The X Factor was created by former “American Idol” judge Simon Cowell is huge across the pond and so it was the coming together of phenomena when the two combined.

One classic moment was when actress Amber Riley, who portrays Mercedes on the show, marched up and sang to Cowell. Riley was rejected when she auditioned for “Idol.” The “Glee” cast is scheduled to perform a tour in London.
