Chenoweth will perform the original song "It's 10 AM, I'm Drunk" when her character, washed-up former glee-club star Rhodes, returns following a failed all-white production of The Wiz.
Here is how Fox describes the episode: "Sue Sylvester revives the school newspaper and decides to print a few inflammatory blind items. The glee club gains a whole new respect for Sam when they discover some interesting new information about his family life. Meanwhile, April Rhodes returns to Lima and tries to convince Mr. Schuester to hit the road with her."
