I need help tabbing out this section of a live 1975 version of "Over The Hills and Far Away" by Led Zeppelin. http://www.youtube.com/watch?v=YcSpIOTtWpk

The part I need help tabbing out is like 4:09-4:20.

It sounds like he is playing the same thing over and over but on different spots on the neck, I just cant figure out what the hell he is playing. At one point I can even hear that heartbreaker lick being played which is 8-7-5 on the high E string.

This is my favorite version of OTHAFA, and that lick and the riff following it are probably 2 of my favorite things I have ever heard from Page and I just want to be able to play it haha.

Also, if anyone is interested in how to play 4:20-4:28ish, I have finally tabbed that out after trying for the longest time.(This first chord in this tab is the chord he hits immediately after he finishes the lick that I need help with)
