Kristin Chenoweth returns in Tuesday’s installment of Glee, an episode entitled “Home.” She’s only one in a string of guest stars who will be appearing in the seven episodes between right now and the season finale (we’ve got spoilers on that episode, too!). Keep reading to find out who’s singing what, and what you won’t want to miss on the finale…

Neil Partick Harris and Olivia Newton-John will both appear on upcoming episodes of Glee to perform (Neil’s singing “Dream On,” Olivia’s crooning her hit “Physical”). Idina Menzel, who plays the Vocal Adrenaline coach, will sing “I Dreamed a Dream” and “Poker Face” in upcoming episodes. And the season finale? It’s going to feature the much-anticipated showdown between New Directions and Vocal Adrenaline at the Regionals competition. The final dance number of the episode is so intense, three back-up dancers were injured during filming (don’t worry, they’re fine now). First aid kits and spray bottles of blood remover were on set to help with damage control.

In other words, it’s going to be awesome.
