Not a correction, but addition to ElaElaElano's tab. 
Got it from watching the Live on KEXP version. 
Only 2 unusual chords are Dm6 and G/Ab. He plays them like this:

Dm6 (xx0201@1)    G/Ab
e |----1---------x---|
b |----0---------x---|
g |----2---------4---|
D |----0---------5---|
A |----x---------5---|
G |----x---------4---|

You can play the G/Ab with the top two strings open and it sounds really nice. 
That's how Connor does it.

This is where it changes each verse, leading into the chorus bit with the high vocals

The bus it came
And everybody loaded in
Twenty-seven strangers
In a moving can

The fluorescent light
Doubled everyone inside
The baby's face reflected
In the shopfronts in the sky

But faces change
And rules they all get rearranged
And photographs
All fade away

The bus broke down
At the graveyard on the edge of town
Twenty-seven strangers
Separate without a sound

So I walked home
Just feeling nothing on my own
Noticing that tree of yours
I've been watching it grow

So that's why I'm late
My dearest one what can I say
And tomorrow it could be the same
When I do it all again
