We've got a bunch of goodies for Glee fans! I was browsing online and discovered that not one, but two performances were released from next week's disco themed episode of Glee. Along with another sneak peek, fans can get a pretty good look at what to expect from the episode (description here and song spoilers here.) Here are some sneak peeks and full performances of Disco Inferno and You Should Be Dancing from Glee's new episode: Saturday Night Glee-ver.
