Ready For The End Of The World lyrics

I know the end is near
I've seen the warning signs
Been preparin' myself
Layin' in supplies
I bought a case of Jack
A box set of Merle
I'm getting ready
Ready for the end of the world

Chorus:
I'm getting ready for the end to come
That final hour it all comes undone
And she drops the bomb
And says she ain't my girl
I'm getting ready
Ready for the end of the world

My neon shelter waits
Where I can go to hide
While the memories burn
I'll be safe inside
With the honky tonk few
Bracing for the worst
I'm getting ready
Ready for the end of the world

Repeat Chorus

Yeah, I'll be ready
Ready for the end of the world
