"Fuck The Romans" by The Horror:

Fuck the Romans coming straight from this Celtic Briton.
Their Caesars, armies, roads, I wish Id never seen 'em.
I was doing well in a tribal society;
I didn't want their "order" and their hierarchy.
Fuck the Romans, Silures, Trivobantes,
Fuck the Romans, Votadini, Brigante.
Fuck the Romans, Dumnonii, Iceni.
Fuck the Romans, fuck 'em.
