Close to the end of the movie, where Tic, Bernadette and Felicia are finally doing the big show they drove across the desert for. Where the song "Finally" is their song. Through out the performance, their make-up and costumes change drastically, and they would have absoulutely have no time to do that during the song, they could not have changed their outfits, make-up and wigs 4 times during a 3 minute song.
