Count the Shadows

The day is almost over, the sunlight is going 
And the people walk in shadows, completely unknowing 
That there’s something lethal in the air that they can’t see 
Now a Time Lord could save me just by turning on a light 
But I don’t think that the Doctor’s gonna show up tonight 
And so I’m trying to remember what the Library said to me 
Gotta focus on all the silhouettes that you can see 
Cuz if the number keeps on changing then you’re no use to me 
So count the shadows, count the shadows 
Cuz they’re edging towards you like a hungry moth to a flame 
So count the shadows, count the shadows 
Cuz if you’ve got more than one, then you’re the victim that they will claim 
In the Library the darkness is waiting to attack 
And some explorers went inside but they ain’t never coming back 
Namely Miss Evangelista, Anita and two guys called Dave 
And the Shadows made four thousand other people disappear 
And they’ve been hungry and waiting for a whole damn year 
For some fresh meat that isn’t gonna register as “Saved” 
An invisible carnivorous aggressive Armada 
And they go by the name of the Vashta Nerada 
A thousand thousand million piranhas in the air 
The tingle on your skin that you feel in the dark 
May be the hungry ones who contemplate leaving a mark 
So when you’re reaching for the light switch, make sure you’re prepared
