Christmas songs will be the theme of the Dec. 5 episode and fall finale on 'Glee,' entitled 'Previously Unaired Christmas.'

Since the world of 'Glee' is currently taking place in spring, the episode is being touted as an episode that took place in December of 2012 but wasn't aired until this year because as Sue Sylvester (Jane Lynch) claims it was deemed too indecent by Fox.

All songs will also appear on the 'Glee: The Music, The Christmas Album Volume 4,' which will be released two days ahead of the episode air date on Dec. 3.

You can catch the ep at 9PM on Fox; 'Glee' will return on Feb. 25, 2014 in its new time slot on Tuesdays at 8PM.
