Can you guess the Christmas song from these obscure lyrics?

In these frozen and silent nights,
Sometimes in a dream you appear,
Outside under the purple sky,
Diamonds in the snow sparkle,

Happy Christmas,
I wrapped it up and sent it,
With a note saying "I love you", I meant it

And in our world of plenty, we can spread a smile of joy
Throw your arms around the world
At Christmas time

Hark, now hear the angels sing, a king was born today,
And man will live for evermore, because of Christmas Day.

Does your granny always tell ya,
That the old songs are the best?
Then she's up and rock 'n' rolling with the rest

He followed a light and came down to a shed,
Where a mother and child were lying there on a bed

Oh yea! Lord, we greet Thee,
Born this happy morning,

I could have been someone,
Well so could anyone,
You took my dreams from me,

Thought I heard you say
You love me,
That your love was gonna be here to stay...

Don't care about the presents,
Underneath the Christmas tree,
I don't need to hang my stocking,
There upon the fireplace

Glorious now behold Him arise,
King and God and Sacrifice!

I have had to fight, almost every night,
Down throughout these centuries...
