Verse 1:
       D5
This river that we ride has always been alive
                                       A5         D5
Oh my soul one hundred million years
       D5
This river that we ride will roll on when we die
                                      A5         D5
Oh my soul one hundred million years


Chorus:
         G5                   D5
And this love, this light, between you and I
    G5                   G5                 A5
Is older than that burning ball of fire up in the sky
                                        D5
And the gale that fills our sail


Verse:
              D5                           
And the lights that shine tonight have always been alive
                                       A5          D5
Oh my soul one hundred million years
               D5                    
Yeah the lights that shine tonight will burn on when we die
                                       A5          D5
Oh my soul one hundred million years


Chorus x2:

And this love, this light, between you and I
    G5                   G5                 A5
Is older than that burning ball of fire up in the sky
                                         D5
And the gale that fills our sail
