How about Men of Harlech?
http://www.youtube.com/watch?v=1K0JTb5or6cMen of Terra stop your dreaming
Can't you see their spear points gleaming
See their despotic banners streaming
To this battlefield
Men of Terra stand ye steady
It cannot be ever said ye
For the battle were not ready
Nova Terrans never yield
From the hills rebounding
Let these war cries sounding
Summon all at Nova Terra's call
The mighty force surrounding
Men of Nova Terra on to glory
This will ever be your story
Keep these burning words before ye
True Nova Terrans will not yield
