Capo 2, but his guitar is a tenor or whatever so might sounds a bit different, 
doesn't particularly matter whether you have the exact same key though, the chords 
are all good. Love this tune, hope this guy makes it big, he's got some talent!

G   C1  G   C1  G   C1   G   G/F#
G                                 G/f#      Em
White lips, pale face, breathing in snowflakes
      C2             G        C1
Burnt lungs, sour taste
G                                      G/f# Em
Light?s gone, day?s end, struggling to pay rent
           C2        G
Long nights, strange men

Am7                              C3                   G?
And they say she?s in the Class A Team, stuck in her daydream
                    D/F#               Am7                          C3
Been this way since 18, but lately her face seems, slowly sinking, wasting
               G?                            D/F#
Crumbling like pastries, and they scream the worst things in life come free to us
          Em          C2         G                       
Cos we?re all under the upperhand, and go mad for a couple of grams
Em                   C2        G
And she don?t want to go outside tonight
          Em                 C2          G 
And in a pipe she flies to the Motherland, or sells love to another man
Em       C2       G       D/F#      Em  C2  G           
It?s too cold outside for angels to fly,          
              Em   C2   G    G/f#
for angels to fly

Ripped gloves, raincoat, tried to swim and stay afloat
Dry house, wet clothes
Loose change, bank notes, weary-eyed, dry throat
Call girl, no phone

And they say she?s in the Class A Team, stuck in her daydream
Been this way since 18, but lately her face seems, slowly sinking, wasting
Crumbling like pastries, and they scream the worst things in life come free to us
Cos we?re all under the upperhand, and go mad for a couple of grams
And she don?t want to go outside tonight
And in a pipe she flies to the Motherland, or sells love to another man
It?s too cold outside for angels to fly, angels to fly

Am7           C3              Em 
An angel will die, covered in white
       G/f#    G
Closed eye and hoping for a better life
Am7                      C3 ?slide-D                   Em   C3   G?  D/F#
This time, we?ll fade out tonight, straight down the line

                    Em   C3  G?  D/F#
Straight down the line

And they say she?s in the Class A Team, stuck in her daydream
Been this way since 18, but lately her face seems, slowly sinking, wasting
Crumbling like pastries, and they scream the worst things in life come free to us
Cos we?re all under the upperhand, and go mad for a couple of grams
And she don?t want to go outside tonight
And in a pipe she flies to the Motherland, or sells love to another man
                          D/F# 
It?s too cold outside for angels to fly, angels to fly
To fly, fly
   D/F#      G           
Or angels to die
