Calm, soothing piano music played while the nine shadow silhouettes dressed in trench coats and hats transitioned from one pose to another in a smooth manner until the silhouetted figures were lining up behind each other so that only a single silhouette would be shown.
Dun dun dun dun
Dun dun dunna dun dun
The sound of a strummed guitar filled the air, and as the chords repeated, two people on either side of the center shadow would glide out and toss their trench coats off to the side, leaving only their hats.
When all nine shadows were lined up -
Knock knock knock
"Can I come in?"
A deep voice playfully asked the question as the 9 shadows pretended to knock on the door,
Then, all nine people grabbed the hats on top of their heads and flung them to the side like a Frisbee.
Click!
Then the bright lights turned on, illuminating the stage and revealing the nine boys, who wore well-fitting black suits and red bow ties.
