On tonight’s all-new episode of Glee, the cast will be recreating scenes and performing songs from Grease. We caught up with Darren Criss at Jesse Tyler Ferguson’s Tie The Knot launch party last night to get his take on the “Glease” episode. “It’s definitely a new favorite,” Criss told InStyle.com. “If you’re a Grease fan, you’re going to love it. If you don’t know anything about Grease, you’re going to want to watch Grease.” Sounds (and looks) like viewers are in for a ride (note the “Greased Lighting” preview above). This week will also see the return of Kate Hudson as Lea Michele’s dance instructor, Cassandra July. Hudson, along with Naya Rivera and newcomer Alex Newell, will be singing “There Are Worse Things I Could Do,” and Criss can’t get enough of it. “It’s so good. It’s wonderful!” he said. So, grab your hair gel, leather pants, and poodle skirts—this screams sing-along. Glee‘s “Glease” episode airs tonight at 9/8c on FOX.
