I came across an email from Julia Lane that I received some time ago, and I don't think it has been posted.

Hi Joe- here's what I have on the "Orange Alphabet /ABC"

Basically it seems to have been created to "educate" young boys during the forming of the Orange Order in 1795

It is discussed here

Merritt actually recites it, but the tune for others I found is, ironically, "The Wearing of the Green". His lyrics, though obviously for the same purpose, are very different than the others. There are gaps where I could not decipher the words

And dark superstition forever's lost it's way

They were God's chosen people and they conquered all their foes

For forty years in the wilderness when by our Saviour led

And they're taken on the Bible to be kept while we're alive

For all the prosecutions that Israel underwent

If a brother he is needy and the word is passed around

To teach all future rebels that Jehovah's laws are right

S is for the Serpent which to Eve did ------    appear
But the Orangeman still meets him when least expected near

T is for the---------   in half
When I was nine and could't see it almost made me laugh

U is for Union; in one   we are met
travel and our precepts ne'er forget

V is for the Virgin; the Saviour she did bear
degree you'll find his first name is written there

W is for our --------------- displayed
And if you can rightly find it you need not be afraid

X, in Exodus it is plainly---------
-------- came from bondage and they gained the Promised Land

Y stands for Yat in the Hebrew alphabet
It has a hidden meaning and you may find it yet

Now with Z I'm sorely troubled, but I'll bid you all adieu
But if you've traveled the road that I have traveled it will be made plain to you
