in this musical extravaganza, sunnydale residents find themselves bursting into song, and flame, when a demon attempts to make dawn his bride.
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.
