Good beginners song.

Disclaimer:
I've heard many versions, and the most prominent on YouTube seems to be an altered 
version of the original sped up by a half step.
There are a few original, non-radio versions though.
If you can't find one, just take everything I wrote here and bring it up a half step and 
play it that way.



INTRO-

-All these riffs follow each other, listen to the song. It would just be difficult to 
show the spacing between each.

RIFF 1:

|--16\---------|
|-------9\-----|
|-----------5\-|
|--------------|

Listen to the song to understand the timing and execution here.


RIFF 2:

|--9-7---------------------7-9-12---9\|
|------9-8-7-5-7-----5-7-9------------|
|----------------5-7------------------|
|-------------------------------------|

Riff 3:


|-------------------|
|-------5-7---------|
|--5h7------5-7\----|
|-----------------0-|


Going into the first chorus, do a slide down from the seventh fret A.


CHORUS-

Most of the choruses (not sure about that grammar, ha ha) follow the same pattern.
It goes...

  Who...       Are You...  Who, Who?  Who, Who?
|-------------------------------------------------|
|-------------------------------------------------|
|------7----7------7----7------7----7------7----7-|
|--0------0----0------0----0------0----0------0---|


On chorus 3, there's a riff that goes as follows:

|-----------------|
|----5--7---------|
|----------5--7---|
|--0------------0-|

It comes after the band says "Who... are you? Who, who? Who, who?" twice, than it goes 
back to the regular chorus riff.


VERSES-

|---------------------------------|
|---------------------------------|
|----7-----5---0-0--3-2-0---------|
|--0-----0----------------2-3/12--|

That's the way you play every verse in the song.
Again, listen for the timing.

BRIDGE-

Following a pause at around 2:20-2:25, the bass re-enters at about 2:55-3:00.

|------------------------------------------------------------------------------|
|------5---------5---------5---------5-----------------------------------------|
|--------5---------5---------5---------5\0------7-----7----7------7-----7----7-|
|--0---------0---------0---------0----------0------0-----0----0------0-----0---|

Following this, it fades out again, and yet again comes back in at about 3:45-3:50...

|-------------|
|---------5---|
|-----7-----5-|
|--0----------| x4


FINAL CHORUS-

The last chorus is the same as every other chorus, but near the end it does a similar 
riff as chorus three:

|-----------------------|
|----------5--7---------|
|----7-7---------5--7---|
|--0-----0------------0-|
      ^
 (Do the two
sevens quick!)

OUTRO-

For the outro, quickly play the open E string 16 times, then the E string 3rd fret (G) 
16 times,
and then the E string 5th fret about 26 times and finally strike the open E loudly and 
let it ring out.
That's all!
