Standard tuning, no capo.

(On the first A chord, Kevin does a little hammer on. To do this, start in the Am 
position and just hammer on the second fret of the B string)

A5                   E5
Marie, you got me thinkin'
                                    A5
Long term and being careful with my drinkin'
            D5                           A5
And looking forward to my holidays and weekends
E5                                A5
Marie, I love the way you got me thinkin'
A5                     E5
But Marie, I'm always workin'
                                           A5
Long drives, bad food, stale air, and such boredom
           D5                                                 A5
When I get home, we'll take a trip or just sit around and do nothing
Rent a movie or something
E5
Whatever gets your blood pumpin'
   A5
My Marie

F#5                   D5            A5
You're all the pretty music that I need
F#5                 D5                  A5
So lay down on that couch and sing for me

(The instrumental is basically the verse, except for the D. On the D, you start out in 
normal position, then move the D up two frets, then do a Dm position on the fifth fret. 
Then you go back to A and continue as normal.)

Then, at the end, you do the Am to A hammer on thing three more times, and end on A.
