The screen lit up, and a high-energy electro pop beat blasted out of the speakers for about 20 seconds.
Many people jumped out of their seats, and a few hiccupped in fright while PD Emily laughed silently from the front.
Then, a high, upbeat voice began singing as lyrics appeared on the screen.
When you walked into the room
Pick me, love me, choose me
Couldn't help myself, couldn't look away
Pick me, love me, choose me
Shining like a firework, a firework
Lighting up my heart and soul, heart and soul
Pick me, love me, choose me
This precious dream I'm chasing here
Pick me, love me, choose me
You're the one I want to take me there
Pick me, love me, choose me
I want to be your star, be your star
To shine for you wherever you are, wherever you are
Pick me, love me, choose me
