Guitar: With apologies to Slash

I spent about four hours today working on the second solo from "Sweet Child O' Mine".

It's pretty easy but I can't figure out the last bit; I've got the tabs but they make no sense to my ear so far.

listen: Sweet Child O' Mine solo 2

I can just barely do the half-step bends, though you'll hear some sourness in there. The whole-step bends are too much, so I have to change them to hammer-ons or slides.

And the end is just a mess; I'm playing the notes from the tab but I have no idea how it's supposed to sound, and clearly sounds nothing like the end of that solo.

I've resorted to slowing down Guitar Hero II in practice mode to see if I can figure out how that ending is supposed to sound. No joke.
