So this song is actually quite easy, i'll just provide the chords because well, you 
alot more by knowing the chords as opposed to every little twiddly guitar part.

NOTE: This is not a transcription of the acoustic version to simulate the acoustic 
on youtube just move everything down 1 1/2 steps

Intro:

Am-G-F

Am       G             F
Laid out,Puking in the back of a
Am        G            F
fancy bar You and your friends in the
Am          G              F
front booth Laughing at my sweet naivety
Am      G       F
And its awkward gravity
Am          G                 F
Three years Saw the decimation of
Am               G       F
the world in you Messiah complex
Am               G                  F             Am
Led a fickle flu to see its antidote and end in you
G
But now I'm gonna leave you

Chorus:

Now I am having difficulty aligning what words the changes take place on
so here is the progression, a simple variation on the first with a Dm thrown in right at 
turnaround, if you listen you will notice it.

F-Am-G-Dm


thats essentially it, listen to the recording to perfectly sync it up but yeah enjoy. It 
sound like they are playing diffrent chords during that infected band aids part, but 
not.

Also to change corresponding chords to power chords if you are doing it electric... or 
it up as you wish.

Feel free to correct me on anything or post questions.
