Evans Blue - Show Me Tabs

Tuning: Drop C

Awesome song and I couldn't believe there were no tabs to this up yet, so I
set about figuring it out myself. I got the intro and the basics to the
chorus, but there's some parts that have confused me. This is unfortunately
not a complete tab, but hopefully it can give someone else a better idea of
how to figure it out. Enjoy!

Intro/Verse: 3x
D|----------------------------------------------------------------------|
A|----------------------------------------------------------------------|
F|----------------------------7-----7------------------------------6----|
C|-------9----12-11-9-------7-----7----------2---5-4-2-------7---4---4--|
G|----------9-------------0-----------0--------2-----------5------------|
C|-----9---------------0------------------2-------------5------4--------|

Pre-Chorus: 1x
D|----------------------------------------------------------------------|
A|----------------------------------------------------------------------|

C|----5-5-5-5-5-5-5-5-7-7-7-7-7-7-7-7-9-9-9-9-9-9-9-9-7-7-7-5-5-5-5-----|
      . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

D|----------------|
A|----3~----5~----|
F|----4~----6~----|
C|----5~----7~----|
G|----5~----7~----|
C|----------------|


Chorus: 2x (I'm not sure that I got the complete chords right, but I know the roots are correct)
D|---------------------------------------|
A|---------------------------------------|
F|---(11)-------(9)----------------------|
C|---(11)---5---(9)----2-----------------|
G|----9-----5----7-----2-----------0-2---|
C|----9-----5----7-----2---0-2-4-5-------|

End chorus on this chord as the intro/verse comes back in
D|------------|
A|------------|
F|------------|
C|-----9------|
G|-----9------|
C|-----9------|

Basically repeat everything above to get through the next part of the song,
and after that things get a little muddled for me. Anyone that can add some
more details, please do so.
