Song about ancient Rome, sung to Home on the Range

Oh Rome [can't remember three syllables]
With your wild Coluseum
And your traffic-jammed Appian Way

Where pizza is best
Though it's hard to digest
And Caesar's the King we obey!

Rome, Rome your so fine
With your crazy SPQR sign!
Where the orgies go on
From each night until dawn
And each Christian is fed to a lion!
