The song "I will always love you", sung by Amber Riley, is dedicated to the death of Whitney Houston four days before the airing of the episode. The song was planned to be in the episode anyway, as the topic was "the greatest love songs".
In the first episode of the show, we see a picture of Rachel's dads in her locker. We see in the photos that one of her dads is African American. In this episode, many people believe neither of her dad's are African American. In fact, Brian Stoke Mitchell is mixed race, part African. He is however noticeably lighter in skin tone than the actor in the photo shown in episode 1.
This is not the first time Lea Michele and Brian Stokes Mitchell have co-stared. Both were in the musical Ragtime (1998) on Broadway. Mitchel played Coalhouse Walker Jr and Michele played The Little Girl.
The songs on Britney's playlist for Santana are: Purple People Eater, Disco Duck, Monster Mash, On Top of Spaghetti, Pac-Man Fever, Osama Yo' Mama, and Diff'rent Strokes
