Chord/Tab song: Somehow to Keep It Going

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]Where theres a w[F#m]ind always b[Em]lowing my m[D]ind
[Em]Red rolls the [F#m]river[Em][A]
[Em]The taste of the [F#m]morning still much [Em]sweeter than [D]wine
[Em]Sun as true as [F#m]ever[Em][A][G]
I go rol[A]ling in the water

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

Cause its s[G]weet, couldnt be sw[A]eeter

Repeat intro

[Em]We was feeling bout [F#m]twice our age, [Em]sitting in the pouring [D]rain
[Em]We was feeling bout [F#m]twice our age, [Em]sitting in the pouring r[A]ain
[Em]Once we was a [F#m]rock, [Em]rolling down the [D]hill
[Em]Now we are the [F#m]hill, trying [Em]trying to keep the rock [A]still[G]
But before you [A]know it, we go rolling in the water

Chorus
Chorus again, but instrumental

Cause its s[G]weet, couldnt be sw[D]eeter
Just watch the [G]colors of the morning [A]fly
[Em] [D]
May not be [G]getting any younger
But my [A]lord were feeling so alive

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