Cotton Jones - Somehow To Keep It Going Chords & Tabs

He always plays the intro facing the drums and I haven't been able to pick it out 
by ear, so let me know if you can figure it out. Also, he plays his G's 
differently, but I haven't figured out what exactly they are. But here's the rest of the song:

Intro: Em  F#m  Em  F#m  Em  F#m  D

Em              F#m         Em         D
Where theres a wind always blowing my mind
Em            F#m      Em    A
Red rolls the river
Em               F#m                Em           D
The taste of the morning still much sweeter than wine
Em             F#m      Em     A    G
Sun as true as ever
        A
I go rolling in the water

Chorus:
D                    G            A
Come on baby let the river roll on      x4

           G                  A                           
Cause its sweet, couldnt be sweeter

Repeat intro
[ Tab from: https://www.guitartabs.cc/tabs/c/cotton_jones/somehow_to_keep_it_going_crd.html ]
Em                  F#m            Em                     D
We was feeling bout twice our age, sitting in the pouring rain
Em                  F#m            Em                      A
We was feeling bout twice our age, sitting in the pouring rain
Em            F#m   Em               D
Once we was a rock, rolling down the hill
Em             F#m          Em                      A     G
Now we are the hill, trying trying to keep the rock still
               A
But before you know it, we go rolling in the water

Chorus
Chorus again, but instrumental

           G                  D
Cause its sweet, couldnt be sweeter
               G                     A
Just watch the colors of the morning fly
             Em                     D

           G
May not be getting any younger
       A
But my lord were feeling so alive

D                    G             A
Come on baby let the river roll on
Lord dont let me lose this feeling
