Sanctus Real - Say Goodbye chords

Here's my shot at "Say Goodbye" by Sanctus Real, from their "Fight the Tide"
album. The strum pattern is pretty weird, so I'm not bothering with that. 
Their guitar is tuned to D Standard (NOT Drop D), so it won't sound right 
if your guitar is in E Standard tuning. A lot of hammer-ons and pull-offs 
on the D string on the 2nd fret. The chord-change timing varies in the intro
and verses, as well. First half of intro,chord changes happen on about the
first and fourth beats; second half of intro, chord changes happen on first 
and third beats. Listen to the song and I think you'll catch it.

Four harmonic plucks on 5th fret, then:

Intro: C   Fsus C   Fsus
       Am  Fsus  Am  Fsus

Verse 1:
C                                 Fsus
 So say goodbye 'cause you'll be leaving soon
C                               Fsus
 I know it's hard, and I'll be missing you
Am               Fsus           C  Fsus
 I know it's time to say goodbye

C                     Fsus
 I know the road has worn you down
C                             Fsus
 You never broke; you always held your ground
Am                Fsus           C
 But now it's time to say goodbye

Verse 2:
C                                 Fsus
 And though you're gone, I remember now
