Lyrics:

I'll sing it one last time for you
Then we really have to go
You've been the only thing that's right
In all i've done.

And I can barely look at you
But every single time I do
I know we'll make it anywhere
Anywhere from here

Light up, Light up
As if you have a choice 
Even if you cannot hear my voice
I'll be right beside you dear

Louder, louder
And we'll run for our lives
I can hardly speak I understand
Why you can't raise your voice to say

To think I might not see those eyes
It makes it so hard not to cry
And as we say our long goodbyes
I nearly do.

Light up, light up
As if you have a choice
Even if you cannot hear my voice
I'll be right beside you dear

Louder, louder
And we'll run for our lives
I can hardly speak I understand
Why you can't raise your voice to say

Slower, slower
We don't have time for that
All I want is to find an easier way
To get out of our little heads

Have heart my dear
We're bound to be afraid
Even if it's just for a few days
Making up for all this mess.

Light up, light up
As if you have a choice
Even if you cannot hear my voice
I'll be right beside you dear.
