C G
Blue eyes when the wind was done
C G
You were lying like a soldier
C G
In the grass, in the grass,
C G
Like the war was over
Blue eyes when you took a breath
It was heavy on my shoulder
Clap your hands, clap your hands
It looks like the worst is over
Blue eyes when the wind was here
You were blown just like a feather
In the trees, in the trees
You were caught inside forever
Blue eyes when you hold your breath
I can breath in deeper
Clap your hands, clap your hands
The grass doesn't get no greener
Blue eyes when the wind was done,
You were carried on my shoulder
Praise the land, praise the land
And all of its placeholders
(dead strum and fade out)
(praise the land, praise the land, and all of its placeholders)
