Glee had its best episode of the spring on April 25. Earning an almost-impossible “A” on Broadway.com’s Glee Report Card, “Lights Out” featured several stellar, Broadway-inspired musical numbers including a full-length, fully-conceived production number of A Chorus Line’s “At the Ballet.” The set-up to the song was that New York roommates Kurt (Chris Colfer), Rachel (Lea Michele) and Santana (Naya Rivera) assisted Vogue.com editor Isabelle Wright (Sarah Jessica Parker) at the New York City Ballet Gala, and each remembered when she/he was first inspired by ballet.
