This is reported to be played with open tuning but what tuning 
exactly  I don't know. I have created a simple version which
gets me by. It involves sliding the Cadd 9 up but leaving
the other strings open. In the chorus there is a flourish
which I play as Em9 054030 and Em7(2) 050430 to get back
to the G  
 
Intro: G repeated to get the rhythm
 
G                
From China to Chinatown New York to Tokyo 
          030010      050030         
C          Cadd9       Em7 
Upstate to down Island From here to there 
 
From the backyard to the wide wide open spaces 
From the steel mills to the wind in your hair 
From the claustrophobic beat of my heart 
to the openness of your smile 
We're in this together going the distance 
right down to the last mile
 
CHORUS
G 
Cos you're my partner You are my partner 
C                          Em9  Em7 Em9
You're my partner for life
 
                      (twice, then  twice with just chords)
 
Up the coast of Africa to the Straits of Gibraltar 
through that tunnel where the birds migrate 
In a hotel room without running water 
and all the clocks are running one hour late 
And on the wall are paintings of couples intertwined 
locked in embraces as if fighting for their lives 
And the warm night air breathes through the open window 
And husbands cling to their wives
 
CHORUS repeat
 
BRIDGE
       050050
        Em7(3)       Em7                                         
Well I know I know I know 
                       030010        030030
         C             Cadd9         Cadd9(2)     
why it just has to be just has to be 
 
Well l know l know l know why 
I'm with you and baby you're with me
 
Let's get out of here and drive up to the ocean 
Out of the city and up the coast of Maine 
Feel the spray and the ancient motion 
Watch the children in the sand watch them play 
From the backyard to the wide wide open spaces 
From the pounding of the surf 
to the gentleness of your smile 
We're in this together going the distance 
right down to the last mile
 
CHORUS repeat
