Jonathan Groff returns to "Glee" tonight -- and we've got a sneak peek at his big entrance, set to Adele's hit song "Rolling in the Deep."
Groff's character, Jesse St. James, returns to McKinley High just in time for prom ... but it's unclear if he's back with noble intentions.
Other songs from tonight's episode include ABBA's "Dancing Queen," Christina Perri "Jar of Hearts" and Rebecca Black's "Friday" (Listen to it here!).
Ryan Seacrest also premiered an original song from the season finale called "Light Up the World," check that out below:
