Intro/Chorus:

Only strum once during the intro, but listen to the song for strumming pattern after that.

  (C)   (f)  (C)   (f)  (C)  (D)  (G)

E|----------------------------------3--|
B|--1----------1----------1---------3--|
G|--0----10----0----10----0----7----0--|
D|--2----10----2----10----2----7----0--|
A|--3----8-----3----8-----3----5----2--|
E|----------------------------------3--|

You can also replace the f chord up there with this:

E|-----|
B|-----|
G|-----|
D|--3--|
A|--3--|
E|--1--|

(its just f but an ochtave higher)

Chorus (Lead Guitar):

This is almost perfect but im not 100%.

E|--8---------------------|
B|-----10--8--------------|
G|------------9--8--7--5--|
D|------------------------|
A|------------------------|
E|------------------------|

Verse:

(once again just listen for the strumming pattern)

 (F)   (C)  (F)  (G)

E|-----------------3--|
B|-------1---------3--|
G|-------0---------0--|
D|--3----2----3----0--|
A|--3----3----3----2--|
E|--1---------1----3--|

E|-------------------------------|
                                            |
                                            |
Another way you can play it is replace the 2nd F chord with a D:

E|-----|
B|-----|
G|--7--|
D|--7--|
A|--5--|
E|-----|
