'Glee' catches disco fever in 'Saturday Night Glee-ver' songs
Really, there were just a lot of fever-related pop culture items in the '70s, right? The rest of the tracks include "Disco Inferno," "How Deep Is Your Love," "If I Can't Have You," "More Than a Woman" and "You Should Be Dancing." While they might not all make the final cut in the episode, you can at least listen to the official versions over at Glee The Music.
If you can't make it to Tuesday, FOX has released the full performance videos of "Disco Inferno" and "You Should Be Dancing." Feel free to watch them while you practice your Hustle and other disco dance moves in anticipation of the episode.
