Some chords that are useful:
   C(I)  D9/11(I)  G6(I)   F2(I)  G(II)  F2(II)
        P        P        P      P
E|--0--------0------10-------8------3------3--
B|--1--------3-------8-------6------0------1--
G|--0--------0-------0-------0------0------2--
D|--2-3-2----4-5-4---9-10-9--7-8-7--0------3--
A|--3--------5------10-------8------2---------
E|----------------------------------3---------

The actual motion at the start of the song is more like this.

E--------------------------------------------------------
B--------------------------------------------------------
G--------------------------------------------------------
D----2-3-2--------4-5-4---------9-10-9---------7-8-7-----
A--3-------3----5-------5----10--------10----8-------8---
E--------------------------------------------------------                                

The additional notes shown after each chord rock up and back to the sus-4 version of the chord; listen to the song and you'll hear where that note goes.

The song starts out like this:

|: C(I) D(I) G(I) F(I) :| (4x, I think)

Then

G(II) F2(II) 4x

G(II)     F2(II) G(II)   F2(II)
Fluffhead was a  man
       G(II) F2(II) G(II)   F2(II)
With a horrible   disease
G(II)     F2(II)  G(II)   F2(II)
Could not find no cure
          G(II)    F2(II) G(II)   F2(II)
Won't you help him if you please?

C(I) D(I) G(I) F(I) C(I) D(I) G(II)
                              Fluff-Head!

C(I) D(I) G(I) F(I) C(I) D(I) G(II)
                              Fluff-Head!

Next verses just like the first:

Fluff came to my door
Askin' me for change
His eyes were clear and pure
But his mind was so deranged

Fluff went to a banker
Askin' for some bills
The banker said, "I ain't got that
But I sure got some powerful pills."
