Yes, I know he plays in C Major, but I have no clue what gauge strings to get for a 
in that tuning so I figured it out in C Standard.
Btw, the low G isn't necessary for this song so I left it out.

Listen to song for rhythm.

Then the part after the first chorus is just straight-forward palm-muted 8th notes on 
5th fret on the low C string, along w/ a few fifth chords thrown in the rhythm. Hardly 
notating out. After that:
|--------- -------|--------- -- -- -- -|
|--------- -------|--------- -- -- -- -|
|----11--12-----11|--12----12-12-12-12-|
|--------- -------|--------- -- -- -- -|
|----9---10-----9-|--10----10-10-10-10-|
|0-0---0-- -0-0---|0---0-0-- -- -- -- -|
The open notes might be fifths in drop tuning. Octaves might have a few slide-ins just 
feel.

Kinda just did this from memory. It's a simple song and I hope this proves useful.

* = pinch harmonic. All pinch harmonics are two octaves higher than regular pitch.
p = pull-off
