We thought we’d share a video promo that gives you a behind-the-scenes peek into the shoot for the “Bad Romance” number, the episode’s lavish Lady Gaga homage. The clip is led by “Spring Awakening” vet and Glee regular Jenna Ushkowitz, along with costars Chris Colfer, Amber Riley and Heather Morris.

You can also enjoy all four of those “Glee” kids (along with Dianna Agron and Naya Rivera) in a full audio clip of “Bad Romance,” along with the recently released “Funny Girl” track. Yes, that Funny Girl; Wicked’s Tony winner and “Glee”s recurring guest, Idina Menzel, gets to revisit Barbra with the title song written for the film that won Streisand her acting Oscar (Menzel serenaded Streisand with “Don’t Rain on My Parade,” from the Broadway and film Funny Girls, at the Kennedy Center Honors a few years ago).

“Glee” lead Cory Monteith gets the lead on two Kiss numbers in the episode, “Beth” and “Sing It Out Loud.” To hear Menzel and “Glee” Broadway baby Lea Michele go Gaga with “Poker Face,” click here and scroll down.
