It is a very simple song in it's most basic form. Of course you add bends, slides, hammers that Led used in his slack key version you wind up with something quite a bit more complex. At first listening you might not even recognize it as the same song. This is the artistry of a musician in it's highest form; taking a song in it's most basic form and interpreting it in the style of the musician. And Led is a master at that.
Here are tabs for the original version:
