In "Heart," airing at 7 p.m. Feb. 14, Mercedes (Amber Riley) sings "I Will Always Love You," the Dolly Parton song Houston performed for "The Bodyguard." The performance was recorded and the episode filmed well before Houston's death Saturday, but the show's producers have decided to dedicate the episode to Houston's memory with a card in the end credits.
Mercedes is still struggling with her affections for both Sam (Chord Overstreet) and Shane (LaMarcus Tinker), which is the impetus for the performance.
Here's the episode synopsis: In honor of Valentine's Day, Will challenges the New Directions to find and perform the world's greatest love songs. Meanwhile, Rory (Damian McGinty) competes with Artie (Kevin McHale) for Sugar's (Vanessa Lengies) love.
Listen to the performance below.
