So Whose Mojo Is Doing The Working Anyway?

Having been on a bit of a Chicago blues binge lately, I've taken a peek at some articles on Wikipedia about Muddy Waters, Howlin' Wolf, etc. Apparently there have been several copyright disputes over Waters' macho classic 'Got My Mojo Working." A judge eventually ruled that "the concept of 'mojo' was public domain, and that the existence of references to mojo was not sufficient to justify a finding of infringement."

You decide. Here's the first version:

Got my mojo working but it just won't work on you
Got my mojo working but it just won't work on you
I want to love you so till I don't know what to do
I got my black cat bones all pure and dry
I got my four leaf clovers all hanging high
I got my mojo working but it just won't work on you
I want to love you so till I don't know what to do
(repeat format, with varied spells: hoodoo ashes, black snake boots, red hot tips, etc.)

Here's Waters' version:

Got my mojo working but it just won't work on you
Got my mojo working but it just won't work on you
I want to love you so bad I don't know what to do
Going down to Louisiana to get me a mojo hand
Going down to Louisiana to get me a mojo hand
I'm going to have all you women, getcha under my command
Got my mojo working, ...

Now, I have never heard the first version, but I have to say that its lyrics offer a little more practical advice. You do have to wonder, though, if "black cat bones," "black snake boots," and "red hot tips" really increase one's mojo - and if so, by how much? Also, the first version says "I want to love you so till I don't know what to do," which is a much different sentiment than Waters' proclamation, "I want to love you so bad I don't know what to do." Maybe I'm splitting hairs but this is mojo we're talking about people.
