F#    C#    G#    D#

This is the intro and main chord structure. The barre chords can get tiring, so you can 
a capo on the first fret and play as if F, C, G, and D, in normal open fingering.


Sometimes the D# is excluded.

At about 1 minute into the song, it changes to

C#    G#    D#   / C  G  D with capo

At 1:43 that section ends with

C#   D#    G#


Between that and 2:05, there is noisy rhythm work that I can't really follow, but then 
goes back to the original chord structure .. kinda. At this point you should be able to 
it out, or you shouldn't be playing this song.
