Read it in the paper, marked the date on the wall

To remind myself to celebrate the day I lose it all
        D5                         Csus4
They made plans to be together.  I made plans to be alone.

Yea the cans are on the limo and the rice is on the ground.

They're headed for the islands, but hell I'm already gone.

Here's to all us haters of old lovers' new last names.

Here's to holdin' up and gettin' right where I belong.

That preacher was my jailer, now this bottle is my bail.

So much for all that prayin' her I do would be I don't.

Outro:
Vamp on D5

*Note* If you prefer, you can play the F/C in place of the Csus4 throughout the song.  
I think the open note sounds better, and is what is being played on the album.
Try both and you'll agree it's very hard to tell.
The F/C looks like this:

D-1
A-1
F-2
C-3
G-3
C-X
