This is an arrangement done by an Australian lounge singer.
Enjoy :)

G
Rippin through flesh is what I do best
E
Tear off an arm Amputate a neck
A
Eyes removed, cranium smashed
D7
Decomposing remains, severed in half


Torsos hang from their own intestines
Raped of all bodily extensions, 
Stumps wreathing with infection
Sufferin a Rancid amputation


My muscles tighten as I feel the rush
I look at your corpse starting gush
Internal rot, beginning to clot
Ill swallow your puss

Scat Solo:
G E A
D7
Sufferin a rancid, Sufferin a rancid
Sufferin a rancid amputation!

Hack, rip, slice. Carve, chop, tear.
Rippin out your eyeballs watch them stare
Tear, rip slice, carve chop hack
Shove the entrails into his sack

G
Dying slowly never to rest, 
E
Nerves are quivering as I rip
A
Removal of life on the blade of my knife?
NC
And now my favourite cannibal corpse lyric off all!
D7                      G              D7  G
Rape the limbless cadaver!
