Well, once you get past the intro, it isn't TOO difficult. Some tricky parts for sure, but it's mostly fairly straightforward. The big thing about EJ though is that he's very particular about how certain things are fingered. He has extremely odd chord shapes he plays out in the intro, and a couple in the song proper. The main theme or the "chorus", he insists that the leading note, that slides down each time MUST be played with the pinky. He admits that yeah, the ring finger is stronger and could be used, but that it doesn't give it the right feel. A little TOO particular, if you ask me, but the dude is amazing, so maybe he's onto something.
