Nick's final dance to "First Time Ever I Saw Your Face" is not the first time this song has been danced to in this competition. Melody and Ryan danced to it in a previous episode.
"Sing, Sing, Sing (with a Swing)" is Mia's favorite song.
The song Melody danced to ("You Can Leave Your Hat On") is from the movie "9 1/2 Weeks." Kim Basinger dances to it in her lover's apartment. The version in the movie is by Joe Cocker.
