Posting this because the other ukulele version is shocking. I've included some of the verses that are often 
missed out for some reason.

F    C    F    F

 F      F7        Bb        F      
Amazing grace How sweet the sound
     F       F           C     C
That saved a wretch like me!
  F        F7        Bb     F
I once was lost, but now am found;
    F          C     F    F
Was blind, but now I see.

      F          F7        Bb       F
’Twas grace that taught my heart to fear,
    F        F       C       C
And grace my fears relieved;
    F        F7       Bb      F
How precious did that grace appear
    F      C       F       F
The hour I first believed.

        F    F7       Bb        F
Through many dangers, toils and snares,
  F      F     C      C
I have already come;
     F          F7         Bb        F
’Tis grace hath brought me safe thus far,
    F          C       F     F
And grace will lead me home.

    F        F7       Bb      F
The Lord has promised good to me,
    F       F      C      C
His Word my hope secures;
   F       F7         Bb      F
He will my Shield and Portion be,
   F       C      F      F
As long as life endures.

     F         F7        Bb          F
Yea, when this flesh and heart shall fail,
    F      F          C      C
And mortal life shall cease,
  F        F7        Bb     F
I shall possess, within the veil,
  F       C       F      F
A life of joy and peace.

    F           F7      Bb         F
The earth shall soon dissolve like snow,
    F      F       C      C
The sun forbear to shine;
    F        F7        Bb     F
But God, who called me here below,
     F     C    F      F
Will be forever mine.

     F          F7        Bb       F
When we’ve been there ten thousand years,
       F       F      C    C
Bright shining as the sun,
      F       F7      Bb         F
We’ve no less days to sing God’s praise
     F         C     F      F
Than when we’d first begun.
