(I think these chords are correct; I don't have the guitar in front of
me to double-check.)

   [G]              [D]       [G]
Amazing Grace / How sweet the sound
     [G]                   [D]
That saved / a wretch Like Me.
           [G]        [C]      [G]
I once was lost / But now, I'm found.
    [G]         [D]    [G]
Was blind / but now, I see.

When we've been there / Ten thousand years
Bright shining as / The sun
We've no less days / To sing God's praise
Than when / we've first begun.
