The majority of the song is composed of power chords -- I think the intro goes something 
this, after the funky bass line:

E|-------------|
B|-------------|
G|-------------|
D|-2-2-2-5-5-5-|
A|-2-2-2-5-5-5-|
E|-0-0-0-3-3-3-|

I imagine you're going to have to improvise it -- The sound is a bit distorted and it's 
to immediately translate the proper chord, but screw around with it for the rest of the 
until you think you've got it. Now, the "solo"-ish part in the middle is rather simple:

E|||--------------------|------------------------|--------------------|
B|||--------------------|------------------------|--------------------|
G|||--------------------|------------------------|--------------------|
D|||--------------------|------------------------|--------------------|
A|||--12----------------|--12----14----12--------|--13----------------|
E|||--------------------|------------------------|--------------------|

------------------------|--------------------|------------------------|

This is one of Kevin's most undeniably "punk rock" songs. Check out the lyrics 
from http://m.kovideo.net/l/k/Kevin-Moore/Holllow.html):
for the last time give me ten cents or a dime
and i'll kick the resurrection off today
in the first place get that book out of my face
man, he never tried to call me anyway
now hanging out with prophets ain't no crime
but i never search for nothing i can't find
jesus had his own life, i got mine
just call me hollow you can call me hollow

i was no place when i saw a pretty face
and she nearly saved my soul before she died
it's a damn shame 'cause i almost got her name
but i'm glad to say i made it home alive
now holding hands with mary ain't no crime
but dressing up like santa's not far behind
tell me about your body fuck your mind
just call me hollow you can call me hollow

if you crash and you fall you can call on me
i'm the one you can trust but you'll never be
it's a choice like this song and it's all on you
if you're right then i'm wrong, what you gonna do?

i've been thinking take up drinking
throw a few bad years away
keep redialing and wake up smiling
maybe he'll be in today

gimme that ol' time religion yeah
gimme that ol' time religion yeah

for the last time give me ten cents or a dime
and i'll kick the crucifixion off today
in the first place get that shit out of my face
it'll only make me happy anyway
acid always gets me so deranged
puts all but one station out of range
and i never watch a channel i can't change
just call me hollow you can call me hollow

gimme that ol' time religion
gimme that ol' time religion
