After what feels like a lifetime of waiting (not so patiently), 'Glee' will return to its regular FOX time slot on Tuesday, Nov. 1 at 8PM ET with an all new episode, 'Pot O' Gold.'

Based on what we've heard so far, the comeback episode promises to be jam-packed full of plot, and Damian McGinty of 'The Glee Project' will finally join the show as Irish foreign exchange student Rory, bringing with him a slew of problems (if the photo above is any indication). While Rory is settling in at Brittany's house, Mercedes will be settling into Shelby Corocan's show choir -- which is undoubtedly going to cause a rift between her and Mr. Schue.

Aaand per usual, 'Glee' will bring out the musical big guns in 'Pot O' Gold.' The cast, led by Artie and Blaine, will try their hand at Katy Perry's viral hit 'Last Friday Night (T.G.I.F.),' which means it's party time at McKinley High. Additionally, big-voiced ladies Mercedes and Santana will take on Christina Aguilera's 'Candyman' and the gang will mix in 'Take Care of Yourself' and Foreigner's 'Waiting for a Girl Like You.'

Should be a good one at the end of this long, long waiting game of a rainbow. Bring it on!
