The 'Glee' Cast Performs 'Don't Stop Believin' ' Live on 'The X Factor' The U.S. leg of the 'Glee' tour may have come and gone, but the show's stars are still flexing their vocal muscles for fans across the pond.

Sue Sylvester and Will Schuester, played by Jane Lynch and Matthew Morrison, introduced the McKinley High Glee Club to eager audiences in the UK, where the cast made a special appearance on Britain's 'The X Factor' results show.

The gang, minus Chris Colfer, performed a spirited rendition of Journey's smash hit 'Don't Stop Believin,' one of the New Directions' selections from last season's 'Sectionals' episodes. Despite Lynch's good-natured jokes at judge Simon Cowell's expense prior to the performance, the notoriously curmudgeonly Cowell was a good sport, even taking part in the standing ovation following the song.
