I can't help thinking of David Essex as the Artilleryman in War of the
Worlds

We'll build shops and hospitals and barracks right under their noses -
right under their
feet! Everything we need - banks, prisons and schools... We'll send
scouting parties to
collect books and stuff, and men like you'll teach the kids. Not poems
and rubbish -
science, so we can get everything working. We'll build villages and
towns and... and...
we'll play each other at cricket!
