Wow, this is a fantastic rendition:
Rock of Ages:
1. Rock of Ages, cleft for me,
let me hide myself in thee;
let the water and the blood,
from thy wounded side which flowed,
be of sin the double cure;
save from wrath and make me pure.
2. Not the labors of my hands
can fulfill thy law's commands;
could my zeal no respite know,
could my tears forever flow,
all for sin could not atone;
thou must save, and thou alone.
3. Nothing in my hand I bring,
simply to the cross I cling;
naked, come to thee for dress;
helpless, look to thee for grace;
foul, I to the fountain fly;
wash me, Savior, or I die.
4. While I draw this fleeting breath,
when mine eyes shall close in death,
when I soar to worlds unknown,
see thee on thy judgment throne,
Rock of Ages, cleft for me,
let me hide myself in thee.
