Nature Anthem
Grandaddy

This isn't in the key of the actual song, but i found these chords sounded good and 
my vocal range better for singing along

 
D
I wanna walk up the side of the mountain,
 
G
I wanna walk down the other side of the mountain,
 
Em                             Am
I wanna swim in the rivers and lie in the sun,
 
D                        A     D
I wanna try to be nice to everyone

 
{loop as long as you like, fade out}
