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 mesmerised 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 defences 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
