Normal Tuning

You play this part 3 times, gradually the bend the C more and more 

        ":the river:"         ":and now speaks:"
  H5                                    C5  A5
I-----I-------------------------------I-------------------------------I
I-----I-------------------------------I-------------------------------I
I-4---I-4-4-4-4-4-4-4-4-4-4-4-4-4-4-2-I-5---2---5---2---5---2---5---2-I
I-4---I-4-4-4-4-4-4-4-4-4-4-4-4-4-4-2-I-5---2---5---2---5---2---5---2-I
I-2---I-2-2-2-2-2-2-2-2-2-2-2-2-2-2-0-I-3---0---3---0---3---0---3---0-I
I-----I-------------------------------I-------------------------------I

The "aah uuhh aahh" part:
After you hit C the last time buzzo hits some harmonics at the 2nd fret 
and hits the strings with his pick heavily .

After that you come back to the H and play something similar to the vocal.

Then this follows:

":and now your so  forgivin`"

 I------I--------------------------------------------I
 I------I--------------------------------------------I
 I-5----I-5-----------------3------------------------I
 I-3----I---4---4-5-----3-4-3------------------------I
 I-3----I-----------4-5-----5------------------------I
 I------I--------------------------------------------I

And then you play some more harmonics on 2nd fret like at the "aah uuhh aahh" part.
