Little Silver Bullet lyrics

Little silver bullet hanging in my head And you know you won't dislodge it 'til I'm dead Got it in my dark days when I ????? And now I think I want to give it back And I can't get to sleep can't hit the sack I don't need this full moon trying to drag me down Cos I'm possessed by something underground Oh Mr Mephistopheles I beg to differ, disagree I don't need you, you don't need me So get off my fucking back Oh little silver bullet, trying to lick my brain And I hope he never shoots me there again Got it in my dark days when I was still a pup And I thought that life was always looking up Yeah I thought that life was always looking up Oh Mr Mephistopheles I beg to differ and disagree I don't need you, you don't need me So get off my fucking back Mr Mephistopheles I beg to differ, disagree I don't need you, you don't need me So get off my fucking back Oh Mr Mephistopheles I beg to differ and disagree I don't need you, you don't need me So get off my fucking back Well get off my fucking back Mmm get off my fucking back Well get off my fucking back
