It's very simple.
D F G
My fingers don't lie. My fingers don't lie. I guess it's nothing.
My mouth it ain't dry. My mouth it ain't fine. My Mouth is nothing.
Tell Sally I'm alive. Tell Sally don't bite.
Tell her she's nothing.
(same chord progression with different melodies for the entire song.)
Verse 2:
My fingers won't budge. My fingers won't move.
I guess they're nothing.
Hey, what's in your womb?
Hey, what's in that wound?
I suppose it's nothing.
(Chorus)
