This tab is for the Zac's acoustic part only... this isn't the electric.

His guitar is tuned a 1/2 step down.

G                                           C              G
Spent the night with a friend of mine and a handle of good whiskey
G                                          C               G
We picked guitars and talked about how the glory days went missin'
C                                   G      D/F#        Em
It didn't take too long to find the truth inside that bottle
C              G             D                G
Cast a-sea so long ago was a message from my father

               C                                      G 
You keep your heart above your head and you eyes wide open
G                                           D
So this world can't find a way to leave you cold
                Em            D/F#             Em D/F# G  
And know you're not the only ship out on the ocean
(Walk up to) C                      D                  
Save your strength for things that you can change
C                    D
Forgive the ones you can't
 N.C
You gotta let it go

G                             C                G
Looking back now on my life I can't say I regret it
G                                            C               G
And all the places that I ended up not the way Ma woulda had it
C                                        G        D/F#       Em
But you only get once chance at life to leave your mark upon it
           C             G                    D
And when a pony he comes riding by you better set your sweet ass on it

(This is the main riff with one harmony)

(Fingerpicking progression)

Like a sweet sunset in Georgia let it go
And like the fear that grabs ahold ya let it go
Let it go
Let it go

I know it's not 100% correct but it's pretty darn good. You should be rocking out to this song in no time!
