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
Fm/Eb = x04432
Fm/Db = 3x4432
Em = x13321
Fm/C = 2x4432
C9 = 212020
C7/Bb = x7897x
C7/Bb (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?

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!
