Intro:  Am  Em  Am  Em  Am  Em  Am  Fmaj7   
 
    Am                         G          Am  
Way up in the mountains on the high timberline  
          G           Dm              G            Am 
there's a twisted old tree called the bristle cone pine  
    F               Am         G            Am      
the wind there it's bitter and cut's like a knife 
    G               Dm     G           Am    Em  Am  Fmaj7 
And keeps that tree holdin on for dear life 
 
 
Hold on it does stand in it's ground  
Standing as empires rise and fall down 
When Jesus was gathering lambs to his fold  
The tree was already a thousand years old 
 
 
Chorus 1: 
        F          C                G         C         
Now the way I have lived there aint no way to tell  
     F            C        G 
when I die if I'm goin' to heaven or hell 
        F           C          G             Am  
so when I'm laid to rest it'll suite me just fine  
   Fmaj7                     G            Am 
to sleep at the feet of the Bristle Cone Pine 
 
 
As I would slowly return to this earth  
What little this body of mine might be worth 
It'd soon start to nourish the roots of that tree 
It would partake of the essence of me 
 
 
Who knows but that as the century's turn 
A small spark of me might continue to burn 
Long as the sun did continue to shine 
Down on the limbs of the Bristle Cone Pine 
 
Chorus 2: 
By the way I have lived there aint no way to tell 
When I die if I'm goin to heaven or hell 
But I'd just soon serve out eternity's time  
Asleep at the feet of the Bristle Cone Pine 
 
Chorus 2 
 
Asleep at the feet of the Bristle Cone Pine
