This is my own interpretation of the song. I'm really sorry for my bad English, 
but I'm doing my best ^^.

Intro: trumpets
|--------------------------------------------|
|--------------------------------------------|
|--------------------------------------------|
|--------------------------------------------|
|-5----5-7-8-12----5--13---13-15-17-16----13-|
|--------------------------------------------|

And then...
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-2--2-2-2-2---------------------2-2-2-2-2--2/5-|
|-0--0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0--0---|
      (I don't know how many "0" are there)

|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-2--2-2-2-2---------------------2-2-2-2-2--2/3-|
|-0--0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0--0/1-|

This...
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-2--2-2-2-2---------------------2-2-2-2-2--2/5-|
|-0--0-0-0-0---------------------0-0-0-0-0--0---|

...and this are repeated twice.
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-2--2-2-2-2---------------------2-2-2-2-2--2/3-|
|-0--0-0-0-0---------------------0-0-0-0-0--0/1-|


|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-2--2-2-2-2---------------------2-2-2-2-2--2/5-|
|-0--0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0--0---|
   (I still don't know how many "0" are there)

|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-2--2-2-2-2---------------------2-2-2-2-2--2/3-|
|-0--0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0-0--0/1-|


And then again this...
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-2--2-2-2-2---------------------2-2-2-2-2--2/5-|
|-0--0-0-0-0---------------------0-0-0-0-0--0---|

...and this are repeated twice...
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-----------------------------------------------|
|-2--2-2-2-2---------------------2-2-2-2-2--2/3-|
|-0--0-0-0-0---------------------0-0-0-0-0--0/1-|

...but with the trumpets which are on the last 2 chords:
|-5--5-5-5-5-|
|-3--3-3-3-3-|

And here comes the chorus (I call it "chorus").
|-------------------------------------------------|
|-------------------------------------------------|
|-------------------------------------------------|
|-------------------------------------------------|
|-5--2--7--9-9--11--9--11/5---5--2--7--3-3-5--3--5|
|-3--0--5--7-7--9---7---9/3---3--0--5--1-1-3--1--3|

|------------------------------------------------------|
|------------------------------------------------------|
|------------------------------------------------------|
|------------------------------------------------------|
|-5--2--7--9-9--11--9--11/5---5--2--7--9-9-9--11-11-11-|
|-3--0--5--7-7--9---7---9/3---3--0--5--7-7-7--9--9--9--|


I think this is the most of the song. In a part the trumpets sound like this:
|----------------------------------------------|
|----------------------------------------------|
|----------------------------------------------|
|----------------------------------------------|
|-5-5-5-5----6-6-6-6----9-9-9-9----10-10-10-10-|
|-3-3-3-3----4-4-4-4----7-7-7-7----8--8--8--8--|

Enjoy!
