Letra Invader de Judas Priest original

I came across a smoking field, pulsating afterglow
I saw a seering 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
We 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
