This is my first tab, but i'm almost positive this is what he's playing. I didn't 
see this tabbed correctly anywhere on the internet so i thought i'd contribute. 
It's definitely not standard tuning like the other tabs are saying.

**The song is in drop C# tuning, as follows (top string to bottom):

C#
Ab
C#
F
Ab
C#



No Capo


F:    x99800
Eb:   x77700
C#:   000000 (open)
C#2:  x55500
Fm:   44400x

(note: I know these are not correct names for chords, just meant to be identifiers)



Intro: 

F  Eb   C# C#2 C# Eb


C#
I came home
         C#2
Like a stone
             C#             Eb
And I fell heavy into your arms
         C#
These days of dust
             C#2
Which we've known
          C#                   Eb
Will blow away with this new sun
   
 
Pre-Chorus
      F    Eb    C#
And I'll kneel down
  C#2  C#    Eb
Wait for now

      F      Eb    C#
And I'll kneel down
   C#2    C#    Eb
Know my ground
    
Chorus
 C#                             Fm   Eb
I will wait, I will wait for you!
 C#                              Fm  Eb
And I will wait, I will wait for you!

C#...

C#
So break my step
       C#2
And relent
       C#                   Eb
You forgave and I won't forget
                  C#
Know what we've seen
               C#2
And him with less
              C#                Eb
Now in some way, shake the excess

Chorus
 C#                             Fm   Eb
I will wait, I will wait for you!
 C#                              Fm  Eb
And I will wait, I will wait for you!
 C#                             Fm   Eb
I will wait, I will wait for you!
 C#                              Fm  Eb
And I will wait, I will wait for you!

 C#
Now I'll be bold
             C#2
As well as strong
         C#                    Eb
Use my head alongside my heart
           C#
So take my flesh
           C#2
And fix my eyes
              C#                        Eb
That tethered mind free from the lies

Pre-Chorus
      F    Eb    C#
And I'll kneel down
  C#2  C#    Eb
Wait for now

      F      Eb    C#
And I'll kneel down
   C#2    C#    Eb
Know my ground


C#  Eb  F  C#2 C# Eb x2

  C#   Eb    F  
Raise my hands
 C#2       C#     Eb
Paint my spirit gold
     C#    Eb  F
And bow my head
 C#2     C#     Eb
Keep my heart slow


Chorus
 C#                             Fm   Eb
I will wait, I will wait for you!
 C#                              Fm  Eb
And I will wait, I will wait for you!
 C#                             Fm   Eb
I will wait, I will wait for you!
 C#                              Fm  Eb
And I will wait, I will wait for you!
