There are other versions of this song using the Fmaj shape bar chord, but I 
find this easier:

d-------xxxx-33-----xxxx-66-
a---333-xxxx-11-666-xxxx-44-
e---111----------444--------

Guitar 2 plays that twice then Guitar 2 joins in for the last 3 (ok, nirvana has 1 
guitar, but it sounds better)

e-----1----    x6
b---1------
 (load up on guns...)

then guitars play

e---1--1--1--1-
b--1--1--1--1--

(hello...)

Untill the chorus which is the verse, played with distortion.


After the chorus is finished, play:

e-------------------
b-------------------
g---------4b--------
d-------------------
a--333-44-----------
e--111-22-----------

Play verse, bridge, chorus, and break again then play the solo:

e-----------------------------------
b-----4-6---4-4b-2-1-2-1------------
g---5-----1--------------3-1-0-3-1-0
d-----------------------------------
a-----------------------------------
e-----------------------------------

e-----------------------------------
b-----4-6---4-4b-2-1-2-1------------
g---5-----1--------------3-1-0-3-1-0
d-----------------------------------
a-----------------------------------
e-----------------------------------

e-----------------------------------------------
b-----------------------------------------------
g---1-0-1-0-1-0-1-0-1-0-1-0-1-0-1-0-1-0-1-0-1-0-
d-----------------------------------------------
a-----------------------------------------------
e-----------------------------------------------

(to play this just sing the verse and bridge in your head)

repeat the verse, bridge, chorus, and break again then keep repeating
the chorus for the end.
