Once More, with Feeling

Two of the show's writers, David Fury and Marti Noxon, have small singing parts. Fury can be seen singing "They Got the Mustard Out" outside the magic shop when Buffy checks to see if other people are singing. Noxon sings about a parking ticket ("I think that hydrant wasn't there") while Giles, Xander, and Anya are walking on the street after Xander and Anya's duet.

Tara runs into a pole in the Bronze while she is performing her back-up dance to "Something to Sing About." While the pole is not visible in the shot, Tara bumping into something before she goes out of frame in the background is noticeable. Likewise, if you look closely, you can see actress Amber Benson desperately trying to suppress a laugh as she straightens out her wardrobe after bumping into the pole.

At the end when the Mutant Enemy logo is displayed, the monster sings "Grr, ah" in falsetto (sung by Joss Whedon).

This episode originally aired at an extended length that ran over the hour-long format (approx. 8 minutes over) and was edited down to fit an hour long time slot for each re-airing. The footage cut included the title and overture, Buffy entering the Magic Box and some corresponding dialog, part of the song "I've Got a Theory", the entire song "What Can't We Face," dialog when Dawn enters the Magic Box, after the song "Under Your Spell," and before the song "I'll Never Tell," a verse of the song "Let Me Rest in Peace," some footage in Dawn's bedroom, Dawn's dance number with Sweet's minions, the end of the song "Why Don't We Dance Awhile," a verse of "Walk Through the Fire," dialog when Buffy first encounters Sweet and after the song "Life's a Show," and the song "Where Do We Go From Here" is shorter along with followed dialog between Spike and Buffy.
