As the other chords' version might sound fine but is completely different to what Rachel 
plays, here is the one given me by a good man who managed to figure it out. It sounds 
really good and fairly close to the original to me.

Here are the (few) chords played:
Fm = x24432
[ch]Fm/Eb[/ch] = x04432
[ch]Fm/Db[/ch] = 3x4432
Em = x13321
[ch]Fm/C[/ch] = 2x4432
C9 = 212020
[ch]C7/Bb[/ch] = x7897x
[ch]C7/Bb[/ch] (Bb down octave) = 078970
Ebsus2sus4 = x02430
Db = 355433
C = 24432
Db6 = 355400
Bbm = 022000
Eb = 577655
G = x4666x

Put a capo on the 6th fret and follow this basic picking (Fm example):
E|---------------|
B|----3-3----3-3-|
G|----4-4----4-4-|
D|---------------|
A|-2-2----2-2----|
E|---------------|

I hope it is clear enough... yes I know that the names of the chords are not related to 
the capo (forgive me), but the fingering is.
Shall we begin then?

Fm                   [ch]Fm/Eb[/ch]            [ch]Fm/Db[/ch]               Fm
Deep deep down under mountains I have heard them call my name
       Em
Will I play their little game and tell them
Fm                       [ch]Fm/Eb[/ch]           [ch]Fm/Db[/ch]       Fm

Fm                    [ch]Fm/Eb[/ch]             [ch]Fm/Db[/ch]        Fm
Deep sleep now, under skies of pressing dark upon my dress
Em                                        Fm
Watch it turn from white to red under the bone clean moon
     [ch]Fm/Eb[/ch]            [ch]Fm/Db[/ch]           Fm
I am clinging to this burning shaking bed

My bloody hands up

Mercy, mercy, I've been caught

Lying with my darkest thought

They grab my wings and pin me to the wall

Oh light please try to hold your ground
Fm                  Em
Lift me up before I drown
    Bbm                  Eb

From the neighbouring town
          [ch]Fm/Eb[/ch]            [ch]Fm/Db[/ch]         Fm
There's a boy who comes to sing upon our street
  Em                                 Fm
I watch him from the window thinking deep deep down
        [ch]Fm/Eb[/ch]        [ch]Fm/Db[/ch]         Fm
He'd be richer if he just became a thief
           [ch]C7/Bb[/ch]
Instead he holds his hands out
Fm                 [ch]Fm/Eb[/ch]
I walk down to the river
          [ch]Fm/Db[/ch]         Fm
Stand and shiver in the wind
      Em                                  Fm
Throw stones to watch them sinking to the icy blue
       [ch]Fm/Eb[/ch]         [ch]Fm/Db[/ch]  Fm
Let it rise above my ankles
        [ch]C7/Bb[/ch]
I don't want this darkness
[ch]C7/Bb[/ch] (Bb down octave)          Fm  C Db6
But the sun just falls from the sky

If anything I wrote is wrong it is because it is 2:38 in the morning... and if it is 
right instead, then thank that good man, as I already said.
Have fun spending - at least - one week learning how to play this song.
I shall soon be writing the tab to Sleep aswell.
Good night for now!
