C                 E7         
As I lay this bread on the ground, 
Am               Fmaj7  (hammer-on b string) 
I know my job ain't done
C                            E7
Leaves the Earth all open faced, 
Am                    Fmaj7 (hammer-on)   C Cadd9 C
And over exposed to the sun
C                          Cadd9 C
If the Earth were a sandwich, 
C (palm mute)        G
We'd get along so well,
 G                   Am Asus4 Am
We could feed everybody,
Am             (arpeggiate C and Cadd9)
With a piece of ourselves
C                 E7
As I lay this bread on the ground, 
Am                    Fmaj7 (hammer-on)
I know my job ain't done
C                           E7
If the Earth were a sandwich
F                     C
Then we could all be one
