Well, if I was directing a production of, say, Bright Lights, Big City, I would start it off as follows:
Jaimie is seen in silhouette at first. Then we see him in full light. Then we see the silhouettes of the main characters in the background lined up side by side. They move downstage. When they reach Jaimie, they are hit with spotlights that bathe them in silhouette. Tad sings, "Are we ready to roll?" The cast and the offstage ensemble responds, "Where are we rolling?" Tad sings, "Into the heart of the night!" The line breaks and everyone starts dancing. The ensemble enters. The rest of the nightclub appears around them.
Butters, go buy World of Warcraft, install it on your computer, and join the online sensation before we all murder you.
