This riff is played throughout the song with some minor variations and fills.   The two
are slight (1/4 tone) and short.  The slide is not used to slide up to the twelfth fret
 Don't forget to use your wah pedal!

It sounds like Rich plays the second ending I have tabbed out here during the first
only (though on the Brothers of a Feather CD/DVD, he plays the first ending twice for the
pre-chorus, most likely because the second ending is tougher to play while having a
on your little finger).  The second pre-chorus just repeats the first ending, and the 
and final
pre-chorus is as follows:

C|--------------------------0-----------------------------|----------------------------------|
A|----4-4-3-3----2-2-1-1----0-----------------------------|--4-4-3-3----2-2-1-1----/--12--0--|
F|----3-3-3-3----1-1-1-1----0-----------------------------|--3-3-3-3----1-1-1-1----/--12--0--|
C|----5-5-3-3----3-3-1-1----0-----------------------------|--5-5-3-3----3-3-1-1----/--12--0--|
F|----3-3-3-3----1-1-1-1----0-----------------------------|--3-3-3-3----1-1-1-1----/--12--0--|
C|----------------------------2-3-4-5--2-3-4-5--2-3-4-5\--|----------------------------------|

That is played right after the solo.  On the repeat, instead of playing the riff on the 
C| string, you immediately
slide up to the twelfth fret, then hit an open F| and right back into the chorus again.  Listen
the song for the timing.
