The Monkees Riu,Chiu

Here are the Monkees at the end of their Christmas show singing a song called Riu,Chiu I believe it is in Spanish. It tells the story of Christ. Here is the english translation.
River, roaring river, guard our homes in safety,
God has kept the black wolf from our lamb, our lady.
God has kept the black wolf from our lamb, our lady.

Raging mad to bite her, there the wolf did steal,
But our God almighty defended her with zeal.
Pure he wished to keep her so she could never sin,
That first sin of man never touched the virgin sainted.

River, roaring river...

He who's now begotten is our mighty monarch,
Christ, our holy father, in human flesh embodied.
He has brought atonement by being born so humble,
Though he is immortal, as mortal was created.

River, roaring river...
