This version sung by Stan Boreson is very similar to the version called RANDOLPH THE FLAT-NOSED REINDEER, sung by Homer & Jethro—see their version above. I don't know whose version came first. "Ragnar" is appropriate since Boreson, as usual, sings his parodies in a Scandinavian accent. You can hear it at YouTube. Note that Boreson has an introductory verse and an extra bridge that are not in H&J's version.

RAGNAR THE FLAT-NOSED REINDEER
As sung by Stan Boreson (& Doug Setterberg)
This is track #06 on their album "I Yust Go Nuts at Christmas"

You know, Oscar, this song about Prancer and Vixen (Ya?)
Sounds mighty fine but the words need some fixin'. (Oh?)
Though the tune's the same,
We've changed old Rudolph's name. (To what, pray tell?)

We call him Ragnar the flat-nosed reindeer—had a funny-looking snout,
So Santa cut his nose off, just to try and smooth it out,
And when he sewed his nose on, Santa got it upside down.
Now ev'ry time the rain falls, poor old Ragnar nearly drowns.
Then one foggy Christmas eve, Santa came to say:
"Ragnar, with your nose so flat,
Won't you tell me where it's at?"
Then Ragnar took a deep breath, and he looked so very strange.
He said, "We're out behind the stockyards. Hoo! How I wish the wind would change!"

(It'll never get well if you pick it.)
(No. Now spell on your bells. Beautiful!)

Ragnar got a Christmas cold; he caught it in his snoot,
And ev'ry time he blew his nose, he found he blew his mind to boot.
Rooty-toot toot!

(Ragnar was a way-out reindeer.)

Ragnar the flat-nosed reindeer wished his nose would glow instead,
But it would never light up, 'cause all his batteries was dead!

(He burnt himself out at an early age.)
