Unchained lyrics - Johnny Cash

I have been ungrateful,
I've been unwise.
Restless from the cradle,
Now I realize,
It's so hard to see the rainbow,
Through glasses dark as these.
Maybe I'll be able,
From now on, on my knees.

Oh, I am weak.
Oh, I know I am vain.
Take this weight from me,
Let my spirit be unchained.

Old man swearin' at the sidewalk,
I'm overcome.
Seems that we've both forgotten,
Forgotten to go home.
Have I seen an angel?
Oh, have I seen a ghost?
Where's that rock of ages,
When I need it most?

Oh, I am weak.
Oh, I know I am vain.
Take this weight from me,
Let my spirit be unchained.
