Wolf's Mouth

I got a wolf's mouth And it suits me I chew the sides out With my sharp teeth I cut my tongue up I make my gums bleed I scare the people That pay to see me When I sing And I see white steam Above your blue face It makes my hands hot It makes my lips bake And the sweat just makes my shirt stick To that scratch across my ribs That space where you fell from And I haven't sewn up since I'm trailing off again And the strain just makes my face tic And it messes with my head That space you tore open Well, I've had trouble closing it
