D A Bm F#m
I don't know if i can find a way to keep
A D E
All the secrets that you told me in your sleep
D A Bm F#m
And i'm amazed that you still find the space to dream
A D E
In the shadows of a town made out of thieves
D A Bm F#m
Who would drown the sound of history repeating
A D E
With the ambulances screaming up the street
Ebm Bb Ebm
So sing to me
B F# B F#
Don't let me fall asleep to the sound of cold machines
B F#
Or the smell of gasoline
B C#
Or the weight of destiny
Ebm Bb Ebm
Don't make me wait
B F#
I've been waiting here all night
B C#
I've been waiting my whole life
D A Bm F#m
A D E
Somewhere the ghosts of factory workers dance
With the ghosts of kids who never had a chance
And we still hear it out our window every night
Like a fistfight in an ambulance
Ebm Bb Ebm
B F# B F#
B F# B C#
Sing me a song, don't let me think too long
About what I'm trying to say
A broken fire escape
Or how long I had to wait
