Watch the Cast of Glee Perform Live(-ish) For Simon Cowell

The cast of Glee has performed live for the most influential humans in the world like Oprah and the president, so it made sense that Fox flew their singing cash cows to the U.K. to perform "Don't Stop Believin'" for Dannii Minogue during The X Factor's live semi-finals results show. Well, not really, but those Glee kids had a Christmas album to promote. So watch, dear Gleeks, as Cory Monteith does not even try to convincingly lip sync to back-up vocals, and Simon Cowell does not even try to look pleased when Amber Riley belts the highest Journey notes in his face. But hey, at least Sue Sylvester was there...via tape.

While this rendition of "Don't Stop Believin'" is nearly identical to every other tour performance of the Journey hit, do take notice of the few innovations last night: like, Dianna Agron's bangs, the inclusion of new cast member Chord Overstreet and the exclusion of fan favorite Chris Colfer, who had a scheduling conflict with the Warblers.
