I've been following a discussion on the Ulster Nation group about a supposed 'Ulster national anthem'. I thought it was interesting (not to mention quite ironic in that it ended with the words "a nation once again"). Not overly fussed on the God references, but a decent effort. (The tune, "Jesus Only" is here and a cheerier, if briefer, version is here).

Follow up:

Raise thy banner, Sons of Ulster
'neath its shadow we will stand
As we call to God in heaven
For his blessing on our land.

And our God enthroned in glory
He will hear our earnest cries
And the ancient land of Ulster
Shall with new born strength arise.

Raise thy banner, Sons of Ulster
Pledge again thy heart and hand
To be ever true and loyal
In the service of our land

Soon will come the dawn of morning
Soon will end the night of pain
And the ancient land of Ulster
Be a nation once again.
