Credit to the person who wacked the chords up,
I believe they are correct and have kept them
the same, I have just added in the tab for the
intro/chorus, which I hope is mostly correct.
I'm not great at tabbing, so apoligies if I'm
way off. I can put corrections in at another
time if either you, or I, notice any, but it
sounds pretty OK to me. I hope it's not too
difficult to read!

I think they play it a whole step down, or a whole
step down with capo on 7 (capo 5 in standard).
I have linked videos at the bottom of them playing
it both ways.

Picking pattern throughout song:

A:

e-----x-------x-------|
B-2---x--2----x--2----|
G---2-x-----2-x-------|
D-----x-------x-------|
A-0---x--0----x-(0)---|
E-----x-------x-------| x4 for each line then:

G:

e-----x-------x-------|
B-0---x--0----x--0----|
G---0-x-----0-x-------|
D-----x-------x-------|
A-----x-------x-------|
E-3---x--3----x-(3)---| x2 and for the last bit:

e-----x-------x--3----x-------x-----|
B-0---x--0----x-------x--0----x--0--|
G---0-x-----0-x----0--x-----0-x-----|
D-----x-------x-------x-------x-----|
A-----x-------x-------x-------x-----|
E-3---x--3----x--3----x--3----x-(3)-|

Intro/chorus:

e----x----x----5-x-----x--------|
B-2--x-3--x-3----x-0-3-x--3-----|
G--2-x--2-x------x-----x--------|

AWe'll (x02220@1)sing love songs about heartbreak, and grief,
          GSing (320003@1)it's not just music, but the pain's not brief.
   AWe (x02220@1)sing, how your love, is like a knife to the back.
           GWell (320003@1)I was stabbed and bleeding, but still begging for attack.

CHORUS:
      (Start intro bit on slow and repeat x2)
But I was looking through slow, slow glass,

Looking though slow, slow glass.

AWell (x02220@1)I heard, you've been singing, I was, what I am.
       GWell (320003@1)I never tried to change you, honey I'm your biggest fan.
       AAnd (x02220@1)I loved you back then, but I don't recognise you now.
        GYeah (320003@1)in fact we're almost strangers, and I don't know how.

CHORUS:
  (Start playing intro bit on slow and repeat x2)
but I've been looking through slow, slow glass

Yeah I've been looking though slow, slow glass
