This is a fantastic song, that's pretty simple to play.
Sexton plays this song in a bunch of different ways, alot of time in open G, but this is 
version I've seen him play that is really simple and doesn't require re-tuning your guitar.

D     x-x-0-2-3-2----------|  (hammer on the A note the first beat of every bar)
Cadd9 x-3-2-0-3-3-|
G/B   x-2-0-0-3-3-|


Verse:

DMet (xx0232@1)an old friend last night, had a cup of coffee
DWe (xx0232@1)talked about all the things that had been going on
DWe (xx0232@1)talked about the old days, we talked about the new days
D (xx0232@1)                                         Cadd9 (x32030@1)           G/BWe (143121@7)talked just about anything but what was really going on

DAfter (xx0232@1)ten long minutes that slowly passed us by
DThe (xx0232@1)tension in the air I could cut it with a knife
DStaring (xx0232@1)out the window and gazing at the menu
D (xx0232@1)                                  Caad9             G/BSuddenly (143121@7)he called my name and he looked me in the eye


Chorus:

            Cadd9 (x32030@1)               G/B (143121@7)                              DHe (xx0232@1)said, I don't know where I'm going and I don't know where I've been.
          Cadd9 (x32030@1)                 G/B (143121@7)                     DAnd (xx0232@1)there's one long road that I traveled just to see you again.
         Cadd9 (x32030@1)               G/B (143121@7)                          DI (xx0232@1)said I don't know where I'm going, I don't know where I've been.
       Cadd9 (x32030@1)               G/B (143121@7)                        DAnd (xx0232@1)it seems I got a little trouble and I need you my friend.

After the last chorus for the "its in the journey...." part just keep playing Cadd9 - 
- D.  You'll hear it.

have fun! :)
