Metal singer performs _Amazing Grace_

Amazing grace, how sweet the sound, That saved a wretch like me. I once was lost, but now I'm found, Was blind, but now I see. T'was grace that taught my heart to fear, And grace my fears relieved. How precious did that grace appear, The hour I first believed. Through many dangers, toils and snares, I have already come. T'was grace that brought me safe thus far, And grace will lead me home. That when we first begun. Amazing grace, how sweet the sound, That saved a wretch like me.
