Dear Mr. Marks,
Thank you for your song submission, entitled "Rudolph the Red-Nosed Reindeer." Full comments follow.
Let's assume for a moment that I grant your initial premise, and that I admit that I know (or know of, as you seem to mean) Dasher and Dancer and Prancer and Vixen, as well as Comet and Cupid and Donner and Blitzen.
If I can then truthfully answer "no" to the question you pose, is it logical to assert as you have that this Rudolph is "the most famous" reindeer?
The others you present as a given. Of course you know them. Everybody knows them. You aren't denying this. It's the very first thing you say, in clear and unambiguous terms.
But do I recall this other one? The very question suggests the possibility that I might not. In fact, the entirety of your song after posing the question seems predicated on the listener having no recollection of this particular reindeer or the details of his life, else the singer would simply be rehashing a story familiar both to himself and his audience.
Are you simply trying to create a buzz about this Rudolph character? Are you, perhaps, his publicist? Is it not possible that he is, at best, the ninth most famous reindeer, assuming that no others of his species have attained fame greater than or equal to the eight others mentioned previously? You provide no criteria for measuring reindeer fame other than name recognition, and it seems clear that he fails to achieve "most famous" status by this measure.
In an instance where the initial premise is not granted (i.e., the listener is unaware of the initial eight reindeer you name), does it not then fall to the person performing your song to provide some background data, perhaps biographical information or anecdotes which illustrate the characters and qualities of the reindeer? Where is this additional data? You included neither footnotes nor endnotes, and your bibliography is also missing.
I would recommend you delete this opening section entirely, if only because it is terribly unwise to begin a song centering on a single character with a recitation of eight other, possibly unrelated characters. Are they the bullies mentioned in your second verse? You never specify.
And who is this Santa person who mysteriously appears in what I can only assume (although the structure is never repeated) is the chorus? Is that his first name, his surname, or some sort of nickname? Is he some sort of communal taskmaster? All you divulge is that he is in possession of a sleigh, and has somewhere to be on the night in question.
From there you skip some crucial plot elements. One assumes that Rudolph indeed accepts the question posed by Santa. And then you leapfrog your story again, concluding that Rudolph will "go down in history" for some reason, even though you haven't told us why this might be true, or even where the sleigh was headed.
