off the album Trouble Is.  Its not too complicated and is played pretty much through the whole song.

standard tuning: EADGBe

e--------------------------------------------------------------------|
B--------------------------------------------------------------------|
G--------------------------------------------------------------------|
D--------0h2-0h2-0---------------------0h2-0h2-0---------------------|
A------------------2-1-0---1h2p1p0---------------2-1-0---1h2p1p0-----|
E--12/-0-----------------3---------3-0-----------------3---------3-0-|

This is how the song starts out and it transitions into the higher pitch as he starts to 
the second half of the verse.
The transition is as follows:

e----------------------------------------------------------------|
B----------------------------------------------------------------|
G----------------------------------0h2-0h2-0---------------------|
D----0h2-0h2-0-------------------------------2-1-0---1h2p1p0-----|
A--------------2-1-0---1h2p1p0---0-----------------3---------3-0-|
E--0-----------------3---------3---------------------------------|

As he switches back into the lower pitch he does the same idea but high to low instead of low to high:

e----------------------------------------------------------------|
B----------------------------------------------------------------|
G----0h2-0h2-0---------------------------------------------------|
D--------------2-1-0---1h2p1p0-----0h2-0h2-0---------------------|
A--0-----------------3-----------------------2-1-0---1h2p1p0-----|
E------------------------------3-0-----------------3---------3-0-|
