you smile at me in total defiance of all decency you've got it down to a science 
that innocent look you've got it practiced real good but i know you'd kill me if you could stand the sight of blood

       C                             G
if i'd been a fly on the wall a little earlier
       C                                        G
if i'd been one of the innumerable flies in this room
       C                             G
if i'd been a fly on the wall a little earlier
G            Bb          D              G

you try to speak but the buzzing's too loud and it's hard to make you loud through the dense black cloud
that surrounds us both that's just as well you call them up let the whole house go to hell

if i'd been one of these flies
i would've lodged myself firmly underneath your eyelid
if i'd been one of these flies a little earlier
it would've been real different around here

G     Bb    D     C
G     Bb    D     C
