This song is performed in standard tuning with a capo on 6 and is fairly easy to play as 
long as you get the timing right.
NB: The numbers in brackets denote the amount of bars you should play this chord for, 
not the amount of strums you should do. It's difficult to convey the strumming pattern 
through tablature so I would advise you to listen to the song to figure out the strumming.

Intro and verses (play twice over before singing begins)
(below are the syllables (from the 1st verse) which are sung at the same time as each 
chord is first strummed to help you with timing)
    'hear'  '-ing'  'see'  'fog'
      (x4)   (x2)   (x2)   (x2)   (x2)   (x2)  (x1)   (x1)
e------0------0------0------0------0------0------1------0-----|
B------1------1------1------1------1------1------1------1-----|
G------2------0------0------0------0------0------2------2-----|
D------2------2------3------2------0------2------3------3-----|
A------0------0------0------3------3------3------3------3-----|
E-------------------------------------------------------------|
Intro Am     Am7    Am7/C   C     C/D?    C      F      F
Verse Am     Am     Am7/C   C     C/D?    C      F      F

The only difference between the intro and the verse is that he plays Am for four bars 
and then moves straight onto the Am7/C chord.

Chorus-y bit
(again I've put the syllables of the words sung at the same time that each chord is 
first played to help with timing)

   'bound' 'new'  'hills'                            'blue'
     (x8)   (x8)   (x2)   (x2)   (x2)   (x1)   (x1)   (x8)

D-----2------3------2------0------2------3------3------2------|

E-----0------------------------------------------------0------|
      Em     F      C     C/D?    C      F      F      Em

The song uses the same chord progression throughout. The only chord used in the song 
which I haven't noted down is a variation on an F chord at 2:33 which is something like:

e---0-----|
B---4-----|
G---2-----|
D---3-----|
A---3-----|
E---------|

And that's it. Happy guitar-ing.
