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)
