This is a great song find a banjo to play with usually its played with a capo on 2
but I find it easier to play it without a capo this is how I play it..it sounds
close i know its not right because it is absolutally crazy once it gets going so
here you go this is only the guitar part no banjo in it.

e--------------------------2-------
b--------------------------2-------
g--2-(repeated by banjo)---2-------
d--2-----------------------2-------
a----------------------------------
E----------------------------------

e----------0-5---------------------
b--------2-------------------------
g------2---------------------------
d----2-----------------------------
a--0-------------------------------
E----------------------------------

Then the banjo and guitar trade off like this 
e-0-00-2-0-
b-2-22-3-2-
g-2-22-2-2-
d-2-22-0-2-(x4)
a-0-00---0-
E----------

Now the famous part
e-------------------     e---------------
b-2-3-5-2-3--2------(x2) b--------2-2----
g----------4--2-4---     g--2-2-4--2-4---
d-------------------     d-2-------------
a-------------------     a---------------
E-------------------     E---------------

then it goes like this 
e--------------------------------------------------------
b--------------------------------------------------------
g--------------------------------0-2---------------------
d-----------0-2-0------0-0-0-2-4----4----------0-2-0-----
a-0-0-0-2-4------4(x2)----------------0-0-0-2-4-----4----
E--------------------------------------------------------

e--------------------------------------------------------
b--------------------------------------------------------
g--------------------------------------------------------
d---------------7-9-7------------------------------------
a----7-7-7-9-11------11----------------------------------
E--------------------------------------------------------

Now it starts to speed up a little bit (Banjo Still echoing guitar)
e-0-00-2-0---00-2-0--------
b-2-22-3-2---22-3-2--------
g-2-22-2-2---22-2-2--------
d-2-22-0-2---22-0-2--------
a-0-00---0---00---0--------
E--------------------------

Then this again only faster
e--------------------------
b-2-3-5-2-3--2-------------
g----------4--2-4(x2)------
d--------------------------
a--------------------------
E--------------------------

Then play this(banjo plays this along with guitar)
e--------------------------
b----------2-2-------------
g-----2-2-4-2-4------------
d---2----------------------
a--------------------------
E--------------------------

Now here is where the song goes crazy and gets really fast
the guitar plays this bass line while the banjo goes nuts....
e----------------------------------------------------------
b----------------------------------------------------------
g----------------------------------------------------------
d----------------------------------------------------------
a-0-2-4-5-0-5-7-0-5-0-9-4-5-7-2-7-7-0-2-0-2-4-5-0-5-7-0-9-7
E----------------------------------------------------------

e-----------------------------------------------------
b-----------------------------------------------------
g--------------(Repeated by banjo)--------------------
d--------------------(0-2-0)---------(0-2-0)----------
a-4-5-7-2-7-7-0-(0-2-4-----4)-0-0-(0-2-4-----4)-0-0---
E------------------------------0-----------------0----

e------------------------------------------------
b------------------------------------------------
g--------(0-2-0)---------------------------------
d--(0-2-4------4)--0-0---------(0-2-0)-----------
a-------------------0---(0-2-4-------4)-0-0------
E----------------------------------------0-------

e------------------------0-00-2-0----------------
b------------------------2-22-3-2----------------
g-------(2-4-2)----------2-22-2-2(x2)------------
d-(2-4-6------6)-2-2-----2-22-0-2----------------
a-----------------2------0-00---0----------------
E------------------------------------------------

then we go back to this even faster
e----------------------------------------------------------
b-2-3-5-2-3-2---------------------2-2----------------------
g----------4-2-4------(x2)--2-2-4--2-4---------------------
d--------------------------2-----------2-2-----------------
a----------------4-7-4-----------------2-2-----------------
E----------------------------------------------------------

then we get back into the thick of things
e-----------------------------------------------------------
b-----------------------------------------------------------
g-----------------------------------------------------------
d-----------------------------------------------------------
a--0-4-5-0-5-7-0-5-7-9-4-5-7-2-7-7-0-0-2-4-5-7-8-9-5-7-0----
E-----------------------------------------------------------

e-----------------------------------------------------------
b-----------------------------------------------------------
g------------------------(BANJO GOES INSANE HERE)-----------
d-----------------------------------------------------------
a-4-5-7-4-7-2-7-7-0-0-2-4-5---------------------------------
E-----------------------------------------------------------

then it ends all nice like this banjo and guitar together hit this chord
e---0---
b---2---
g---2---
d---2---
a---0---
E-------

AND THATS DUELING BANJOS....Note: once again this was done by ear i know its not
100% correct but its pretty close it doesn't sound like much without a banjo since the guitar takes 
the bass line when the song gets fast
just to let you know.. so to get timing and speed down play it with the 
recording...have fun with it
