The cast of Glee -- minus Chris Colfer -- made a special appearance on Britain's The X Factor talent show Sunday and even performed live, and RadarOnline.com has the clip.
The cast sang one of their signature songs, the Journey classic, Don't Stop Believin', one of the New Directions' tunes from last season's Sectionals episodes.
Sue Sylvester (Jane Lynch) and Will Schuester (Matthew Morrison) made a comical special appearance via videotape to introduce the McKinley High Glee Club to the audience and to the judges, which includes Simon Cowell.
Colfer, who plays openly-gay Kurt on the show, couldn't made the trip as he had to tape scenes with the Warblers back in Los Angeles.
Glee airs Tuesdays at 9/pm ET/PT on Fox. This week's episode is titled, A Very Glee Christmas.
