Here is the mandolin lead part. I think it is very close to 
correct. I tabbed this from their live album "Live Two Five"
I believe it is the same as their other recordings, but I'm
not sure if the live version is different than others.

The mandolin chords are exactly what jeffrey_brent has
for the guitar chords. The major rhythm of this song is 
formed by mandolin chords. 




e ----------------------------------------------
a --------0-1/2-020--------02-3--0-2-0--0-------
d --0-2h4------------5--045--------------520-025
g ----------------------------------------------

e --------------3p0-0---------------------------
a -0-2-5-2-5-2-5---5--5-22-3-2h3p2p0------------
d ----------------------------------5-----------
g ----------------------------------------------

e -7/3p0-0---------------------------
a ------5--5-2-5---7t---9t---10t-----
d -----------------5t---7t---8-t-----
g -----------------------------------



Then this short little sequence starts a few bars later 

e -7-7---5-5---3-3-----3-3---5-5---3t----
a -5-5---3-3---2-2-----2-2---3-3---2t----
d ---------------------------------------
g ---------------------------------------

Then it goes back to rhythm
