Here's how Fox describes the Nov. 8 episode: "Under Artie’s (Kevin McHale) directorial leadership, the kids prepare to perform the school musical West Side Story. Meanwhile, Finn (Cory Monteith) meets with a recruiter, and Coach Bieste (Dot-Marie Jones) has an admirer."

Fox offers a behind-the-scenes look at filming Billy Joel's "Uptown Girl." Blaine and the Warblers perform a cover of the song, which was featured in the 2002 Broadway musical Movin' Out. Also, the McKinley High students talk about taking on "The First Time," an episode that tackles many "firsts" for the New Directions.

When Blaine (Criss) makes his return to Dalton, he will have his first encounter with Sebastian (Grant Gustin), a new gay student at Dalton Academy who tries to interfere in his current relationship with Kurt.

Also, as McKinley High prepares to put on its first big musical, the Leonard Bernstein-Stephen Sondheim-Arthur Laurents classic West Side Story, the students will perform covers of "America" and "A Boy Like That."

"Glee" airs Tuesday nights on Fox at 8 PM ET. To watch the behind-the-scenes action with Criss and the Warblers, look below:
