Hammer on the low E string while playing the G chord. 

G
I grew up in a military town
G
Waitin' on the sky to fall
G                               D
Everybody I knew hanqin' around wonderin'
                        G
What they'd do when the Draft Board called
G
Lookin' back it musta been a miracle
G
How I ever grew up at all
G
To sing about livin' in a military town
D                     G
Waitin' on the sky to fall

[Chorus]

C (Strum loud)
Waitin' on the sky to fall, boys
G
Waitin' on the sky to fall
G
Chicken Little wasn't makin' nothin' but noise
D                     G
Waitin' on the sky to fall


[Verse] Repeat chords

Spent a lonely lifetime rollin' down the line
Searchin' for the Holy Grail
Never once crossed my solitary mind
That any such consecrated quest'd fail
Came upon an ocean and much to my chagrin
They told me that ship had sailed
Walkin' on the water cause I never learned
To swin searchin' for the Holy Grail

Searchin' for the Holy Grail, friends
Searchin' for the Holy Grail
Been across the oceans and now I'm back again
Searchin' for the Holy Grail

Been around enough to know a little bit now
And I'm sitting on tip of the world
Wangin' on a guitar while the sun goes down
And singin a song about a redheaded girl
Was a time I would have said those days were gone
But I'm givin' it another whirl
Didn't know that I was gonna live this long
Now I'm sitting' on top of the world

Sittin' on top of the world, y'all
Sittin' on top of the world
Eyes wide open until the Messenger calls
Sittin' on top of the world
