Letras:Judas Priest. Stained Class. Invader.

I came across a smoking field
Pulsating afterglow
I saw a searing flash of light
Erupt and skyward go
I staggered back in dazed surprise
What was it I had seen?
And as I stood there mesmerized
I heard my spirit scream

Invader, invader nearby
Invader, invader is nigh

This is the first of more to come
In carefully planned attacks
If it is so we must prepare
Defenses to fight back
The call is out throughout the world
United we must stand
To build a line, strategic force
They will not take a man

Invader, invader nearby
Invader, invader is nigh

When they come to take control
Every man must play his role
They won't take our world away
When the children we leave
Will have to believe in today

We warn you now you things out there
Whatever you may send
Won't give in without a fight
A fight until the end
With vigilance by day and night
Our scanners trace the sky
A shield is sealed upon this earth
A shield you won't get by

Invader, invader nearby
Invader, invader is nigh
