I believe he plays this with 2nd fret capo on 5 strings with an open low E string
[Intro]
D A Em (4x)
D A Em
In the dark you can sometimes hear your own heartbeat
D A Em
Or the heart of the one next to you
D A Em
And the house settles down after holding itself up all day
D A Em
Shoulders slump, gives a big sigh
D A Em
You hear no one’s foot fall in the hall
D A Em
That drip in the kitchen sink keeps marking time
D A Em
June bug on the window screen can't get in, but keeps on trying
D A Em
One way or another we're all in the dark
[Chorus]
A G
Fireflies and sparks and lightning and stars
A G
Campfires, the moon, headlights on cars
A G (hold)
The Northern lights, the Milky Way
You can't see that stuff in the day
D-A-Em (4x)
D A Em
The Earth turns its back on the sun
D A Em
And the stars come out and the planets start to run, around
D A Em
They call that 'day is done
D A Em
But really it's just getting started
D A Em
Some folks take comfort in that
A G
How dark is it? It's too dark for goblins
A G
How dark is it? It's so dark you can smell the moon
A G
How dark is it? It's so dark the wind gets lost
A G
How dark is it? So dark the sky's on fire
A G (hold)
How dark is it? It’s so dark you can see Fort Worth from here
(D-A-Em) x 6 then (D)
