So the main chord played through most of the song is this (listen to the song for the rhythm):
E|---------------------------------------------------------------------------|
B|---5-----------------------------------------------------------------------|
G|---4-----------------------------------------------------------------------|
D|---3-----------------------------------------------------------------------|
A|---------------------------------------------------------------------------|
E|---------------------------------------------------------------------------|

Then it goes into the chorus with:
E|---------------------------------------------------------------------------|
B|---------------------------------------------------------------------------|
G|---4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-------------------------------------|
D|---5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-------------------------------------|
A|---3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-3-------------------------------------|
E|---------------------------------------------------------------------------|

Then play the separate notes to Ryan's voice just once, so:
E|---------------------------------------------------------------------------|
B|---------------------------------------------------------------------------|
G|------4-4------------------------------------------------------------------|
D|----------5-5-3-3----------------------------------------------------------|
A|--3-3----------------------------------------------------------------------|
E|---------------------------------------------------------------------------|

Then finish up the chorus with:
E|---------------------------------------------------------------------------|
B|---------------------------------------------------------------------------|
G|---------------------------------------------------------------------------|
D|-2-2-2-2-2-2-2-2-2-2-2-2/4-4-4-4-4-4---------------------------------------|
A|-3-3-3-3-3-3-3-3-3-3-3-3/5-5-5-5-5-5---------------------------------------|
E|-3-3-3-3-3-3-3-3-3-3-3-3/5-5-5-5-5-5---------------------------------------|

Then back to this for a while:
E|---------------------------------------------------------------------------|
B|---5-----------------------------------------------------------------------|
G|---4-----------------------------------------------------------------------|
D|---3-----------------------------------------------------------------------|
A|---------------------------------------------------------------------------|
E|---------------------------------------------------------------------------|

And at one point in this verse he has a little slide and plays a couple of bars here:
E|---------------------------------------------------------------------------|
B|---5/10--------------------------------------------------------------------|
G|---4/9---------------------------------------------------------------------|
D|---3/8---------------------------------------------------------------------|
A|---------------------------------------------------------------------------|
E|---------------------------------------------------------------------------|

Then the chorus happens again and leads into this little solo thing Ryan does:
E|-------------------------------------------------------------------------------------------------|
B|-------------------------------------------------------------------------------------------------|
G|-------------------------------2-2-2-------------5-5-5-4-4-4-7-7-7-9--9-9-9--14-14-14-13-13-13---|
D|-------------------------3-3-3-------5-5-5-4-4-4-------------------------------------------------|
A|-------------3-3-3-2-2-2-------------------------------------------------------------------------|
E|-3-3-3-2-2-2-------------------------------------------------------------------------------------|

E|---------------------------------------------------------------------------|
B|--9-7-5-3-----------------9-7-5-3-15-15-15-17-17-17-17-17------------------|
G|--9-7-5-3-1-1-1-1-3-3-3-3-9-7-5-3-14-14-14-16-16-16-16-16------------------|
D|---------------------------------------------------------------------------|
A|---------------------------------------------------------------------------|
E|---------------------------------------------------------------------------|

The chorus happens once more then end on a final:
E|---------------------------------------------------------------------------|
B|---5-----------------------------------------------------------------------|
G|---4-----------------------------------------------------------------------|
D|---3-----------------------------------------------------------------------|
A|---------------------------------------------------------------------------|
E|---------------------------------------------------------------------------|
