Cocaine cannot kill my pain. Like a freight train through my vein. Cocaine cannot kill my pain. Whiskey got no hold on me. Left them chains in Tennessee. Whiskey got no hold on me. Don't come knockin' on my door. Even that won't work no more. Don't come knockin' on my door. Heroin is the only thing. The only gift the darkness brings. Heroin is the only thing. Guess you'd best leave me alone. At least until these blues have gone. Guess you'd best leave me alone
