Here, Lea Michele sings Katy Perry's hit song 'Firework'. Will Rachel light up the sky this week? Listen below!

With the biggest budget in the history of the mega-hit GLEE - all-too-befitting of the post-Super Bowl expectation-heavy extravaganza, whatever the network or entity - how did the highly-awaited return of the hottest show on TV fare in its raptly anticipated - making the most vociferous among the gleeks near-rapacious - super-duper Sunday special edition and how did it score across the board? How does it measure up to the massively successful Season One and the best of the best of the rest? What about side-by-side with Season Two? See why 'The Sue Sylvester Shuffle' was a Super Bowl stunner or a lamentable loser of a let-down in this play-by-play recap of the biggest (ostensibly) Broadway-related event of 2011 - at least until the Tony Awards in the Spring; not counting SPIDER-MAN (but that isn't a 'musical' anyway, right?). See who scored big and see if anyone fumbled - and who, at the end of the game, made the stadium truly rock.

The episode featured the return of Gwyneth Paltrow, a guest appearance by Katie Couric and a performance of Michael Jackson's 'Thriller'. Now in its sophomore season, GLEE is a biting musical comedy that has quickly become a pop-culture phenomenon.

Grab a slushie and wear your McKinley colors with pride, Gleeks! Glee is back and bigger than ever! Bored with her current routines, Sue decides to spice it up by launching Brittany from a cannon. However, once Principal Figgins finds out, Sue goes berserk and goes on the war path - her targets being the usual Glee Club, and now the football team. The McKinley Titans and The New Directions animosity reaches a boiling point, thus forcing Coach Bieste and Mr. Schuester to force their teams to work together for a week. Rachel and Puck perform Lady Antbellum's'Need You Now' to show the Titans how New Directions works, with less than stellar results. After Sue, still on the war path gets the Regional Cheerleading competition switched to the same day as the Championship Football game, thus resulting in some sticky moments for New Directions and The Titians. However, Coach Bieste and Mr. Schuester form a plan around the idea of performing Michael Jackson's Thriller mashed with The Yeah, Yeah's 'Heads Will Roll'.
