This is my take on the song and by ear it's pretty accurate.
Standard EADGBe Tuning.
VERSE 1
Gb
I stayed in one place for too long
Gotta get on the run again
I saw the one thing that I want
Hell bent, get outta bed
E
I'm throwing rocks at your window
You're tying the bed sheets together
They say we are dreaming too big
I say this town's too small
CHORUS
Gb
Dream
A
Send me a sign
E
Turn back the clock
B
Give me some time
D
I need to break out
A
And make a new name
E
Let's open our eyes
B
To the brand new day
It's the brand new day
Gb
ah ah ah ah ah ah ah ah ah
Gb
ah ah ah ah ah ah ah ah ah
VERSE 2
Gb
I've taking hits like a brother
But I'm getting back up again
And from the moment I saw her
I was hell bent with heaven sent
E
I'm throwing rocks at your window
We're leaving this place together
They say that we're flying too high
Well get used to looking up
CHORUS
