I remember someone asking for Godzilla by Blue Oyster Cult, and I happen
to know how to play that one:

Main Riff:
-------------------------------------------------------------------
-------------------------------------------------------------------
-------------------------------------------------------------------
-------------------------1--2------------------------------1--2----
---------2--4------0-0---------2--------2---4------0--0--------2--
---2-2---------4-----------------2--2-----------4----------------2-

it also switches to an octave higher at some point:

--------------------------------------------------------------
------------------------4--5----------------------------------
--------4--6-----------------4--------------------------------
---4-4--------6--7--7-----------4--4-------------------------
--------------------------------------------------------------
--------------------------------------------------------------

Just before the lyrics start there is a series of high F-->F#-->E riff(notes,
not chords)

Chord progession during lyrics:
F#m  A

During chorus:
E                                     F#m
Oh no, they say he had to go go go godzilla


this should get you started.  But lots of reverb & distortion & fx on and
it is really fun to play.

PS- looking for the riff to Genesis: throwing it all away, if anybody
out there knows it...
