Here Comes Santa Claus

I am trying to find some information on this song to find out which verses are from the original version from the '40's, and which (if any) have been added over the years. Any music historians out there able to help?

HERE COMES SANTA CLAUS

Here comes Santa Claus, Here comes Santa Claus
Right down Santa Claus Lane.
Vixen and Blitzen and all his reindeer are pulling on the reins.
Bells are ringing, children singing, all is merry and bright.
Hang your stocking and say your prayers,
'Cause Santa Claus comes tonight.

Here comes Santa Claus, here comes Santa Claus
Right down Santa Claus Lane.
He's got a bag that's filled with toys for boys and girls again.
Hear the sleigh bells jingle, jangle, what a beautiful sight.
Jump in bed, cover up your head,
'Cause Santa Claus comes tonight.

Here comes Santa Claus, here comes Santa Claus
Right down Santa Claus Lane.
He doesn't care if you're rich or poor, for he loves you just the same.
Santa knows that we're God's children, that makes ev'rything right.
Fill you hearts with Christmas cheer,
'Cause Santa Claus comes tonight.

Here comes Santa Claus, here comes Santa Claus
Right down Santa Claus Lane.
He'll come around when the chime ring out, then it's Christmas morn again.
Peace on earth will come to all if we just follow the light.
Let's give thanks to the Lord above,
'Cause Santa Claus comes tonight.

My reason for asking is that I don't remember hearing the last two verses in some arrangements. I have some theological issues with "Santa knows that we're God's children, that makes everything right" and "Let's give thanks to the Lord above 'Cause Santa Claus comes tonight." I get the feeling that those lines in particular trivialize the real reason for Christmas. We need to be careful blending secular and commercial traditions with religious beliefs.

Ah well, it's just me sounding off yet again -- any help or comments appreciated.
