Tuning:Standard
Capo on 9 (or 7 depending on version)
He hardly picks the 1st string (only with the D chord).
He does some hammer-ons/pull-offs on the 2nd string when playing the G chord in the intro.
You'll have to listen to the song to get your picking. Enjoy!

    it's been years
         Am7             G
since we     carved our names
     Am7             G
on a     clocktower door
       Em           D
before everything changed
Am7           G
we were     big eyed boys
         Am7               G
with the     salt on our skin
         Am7            G            A7
and we'd     throw our kites to the wind
Em     G      C  C/B Am7
and they'd fly on and on and on and on
Em        G      C  C/B Am7
   on and on and on and on
Em        G      C  C/B Am7...
   on and on and on and on

since we     whispered soft
         Am7             G
with the     torch light on
        Em        D
and the big light off

we were     tired boys
         Am7              G
with the     soap on our skin
         Am7         G           A7
and we'd     fall asleep to the wind
Em     G      C  C/B Am7
and we'd dream on and on and on and on
Em        G      C  C/B Am7
   on and on and on and on

we're circles you see
       G               Bm7
we go round round the sun
       C    C/B      Am7
in and out like the sea

you will circle round me

    and in years
         Am7              G
when the     torch light thins
        Am7                G
and the     clock tower's gone
        Em         D
and the big light dims
Am7            G
we'll no     longer be boys
           Am7               G
we'll have     lines on our skin
            Am7            G               A7
and they'll     throw our dust to the wind
