Down with the Ship by Enter the Haggis guitar chords

This was the first real song I figured out on guitar, and I was inordinately proud of myself for getting three chords correct . . .

Intro/instrumental
A D A G D A

verse:
        A                           D       A
Like ships in a squall we rise and we fall
          G                 D                           A
We're plotting our course through the waves
A                                     D    A
Some masts are tall with sails so strong
G                 D                 A
Others are tossed in the gale
       A                          D              A
We try to stay dry with salt in our eyes
      G               D              A
No moment to rest or complain
       A                       D           A
The moon isn't far a clear sky and stars
G               D                    A
Red sky at morn on your tail
A

chorus:
      G                  D               G               A
I'm not going to stand on the end of the pier
     G                   D              A
I'm not going to let you go down with the ship
G                     D              G          A
Raise up your anchor it's time to set sail
     A                 D/    
I'm not going to let you go down
D

verse:
Like ships we were made to dance o'er our graves
One false move and we could be thrown
Buried alive before our due time
To rest at sixty below
So jibe while you can if there's danger ahead
Stay on your course if you will
I'll throw you a line as waves start to rise
Bail as your ship starts to fill

instrumental:
A / A / D / A
G / D / A / A

outro:

repeat ad infinitum
