Your song in G

[Verse 1]
G            G7          C       G
Amazing grace, how sweet the sound
G                      D
That saved a wretch like me
G            G7         C        G
I once was lost, but now am found
       Em       D        G
Was blind, but now I see
 
[Verse 2]
G              G7         C      G
'Twas grace that taught my heart to fear
G                       D
And grace my fears relieved
G              G7        C         G
How precious did that grace appear
        Em      D        G
The hour I first believed
