Kurt (Chris Colfer) gets to belt out Victor/Victoria's "Le Jazz Hot" all by himself, plus sing with Rachel (Broadway baby Lea Michele) in an homage to Judy Garland and Barbra Streisand on "Get Happy/Happy Days Are Here Again." Harry Shum, Jr., who plays Mike, will finally raise his voice in song – sort of – in an amusing twist on the classic A Chorus Line number, "Sing!," which Mike performs with his new love, Tina (Spring Awakening vet Jenna Ushkowitz).
Other duets to be featured in the episode include Mercedes (Amber Riley) and Santana (Naya Rivera) on the Ike and Tina Turner favorite "River Deep – Mountain High," Sam (cast newcomer Chord Overstreet) and Quinn (Dianna Agron) on Jason Mraz and Colbie Caillat's "Lucky" and Rachel (Michele) and Finn (Cory Monteith) on the Elton John-Kiki Dee standard "Don't Go Breaking My Heart."
