G|-----2-.-------2-.-------------|
D|---2---4---4-4---4-------------|
A|-4-------------------4-4-4-4-4-|
E|-------------------------------|

Then this is through most of the song:

G|---------------2-.-------------|
D|---2-3-4---4-4---4-------------|
A|-4-------------------4-4-4-4-4-|
E|-------------------------------|

Here is my version of the guitar rhythm that enters next:

E|---------------------------------------| |
B|--------------------------------------| :||
G|---------------------------------------| |
D|---------------------------------------| |
A|------4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-| :||
E|------2-2-2-2-2-2-2-4-4-4-4-4-4-4-4-4--| |
     pm.  . . . . . . . . . . . . . . .
                                ^ ^ ^ ^
                          Note 1: you can hear some chord shifting because
                                  he plays the second chord differently --
                                  you can try this one: -6-  or  -6-|
                                                        -4-      -4-|
                                                        ---      -4-|

Before the change, only the first chord of the previous rythm is used,
then the next part goes:

E|---------------------------------------------------|
B|---------------------------------------------------|
G|-6-6-6-6-6-----------------4-4-4-4-4---------------|
D|-6-6-6-6-6---2-2-2-2-2-2---4-4-4-4-4---6-6-6-6-6-6-|
A|-4-4-4-4-4---2-2-2-2-2-2---2-2-2-2-2---7-7-7-7-7-7-|
E|-------------0-0-0-0-0-0---------------------------|
                                       ^ ^ ^ ^ ^ ^
                                   Note 2: he probably plays more notes in
                                           this chord and plays it lower on
                                           the neck, or maybe it's wrong.
                                           Try something like: -1-
                                                               -2-
                                                               -2-
                                                               -0-

Then we have this part, a variation of the main rhythm:

E|------------------------| ---|
B|------------------------| Note 3:              ---|
G|----------------6-6-6-6-| the chord that       -9-|
D|-4-4-4-4-4------6-6-6-6-| is added sometimes   -9-|
A|-4-4-4-4-4------4-4-4-4-| (e.g. at the end of  -7-|
E|-2-2-2-2-2--------------| the song) is an E:   -0-|

A cooler variation of this part appearing a few times is:

E|----------------------------------|
B|----------------------------------|
G|-------------------------6---6----|
D|---------4-----4---------6---6----|
A|---------4-----4-4-4-4-4---4---4--|
E|-2-2-2-2---2-2--------------------|
