This week's 'Thanksgiving' episode of 'Glee' (yeah, it's a week late) finally reveals the cast's take on Psy's 'Gangnam Style' and also features covers of recent hits by Flo Rida and One Direction.

As New Directions gear up for sectionals, they receive a visit from recent McKinley High grads who stop by to mentor them. The group's 'Gangnam Style' performance is a must-see, while the Warblers tackle 1D's 'Live While We're Young' and Flo Rida's 'Whistle.'

Perhaps the most intriguing song in 'Thanksgiving' is a group number from Quinn, Puck, Mercedes, Mike, Santana, and Finn, who join together for a medley of Phillip Phillips' 'Home' and the Simon & Garfunkel classic 'Homeward Bound.'

The episode also features Rachel and Kurt enjoying a non-traditional Thanksgiving dinner in New York. They join Isabelle and Brody to sing a mashup of the Scissor Sisters' 'Let's Have a Kiki' and the 'Promises, Promises' musical number 'Turkey Lurkey Time.'

'Thanksgiving' airs on Thursday, Nov. 29. Scroll down to hear some of the performances from the episode.
