Amazing grace original singer?

who was the originally singer of amazing grace

Amazing Grace is a well-known Christian hymn. The words were written late in 1772 by Englishman John Newton. They first appeared in print in Newton's Olney Hymns (1779), which he worked on with William Cowper.

Amazing grace, how sweet the sound
That sav’d a wretch like me!
I once was lost, but now am found,
Was blind, but now I see.

’Twas grace that taught my heart to fear,
And grace my fears reliev’d;
How precious did that grace appear,
The hour I first believ’d!

Thro’ many dangers, toils and snares,
I have already come;
’Tis grace has brought me safe thus far,
And grace will lead me home.

The Lord has promis’d good to me,
His word my hope secures;
He will my shield and portion be,
As long as life endures.

Yes, when this flesh and heart shall fail,
And mortal life shall cease;
I shall possess, within the veil,
A life of joy and peace.

The earth shall soon dissolve like snow,
The sun forbear to shine;
But God, who call’d me here below,
Will be forever mine.

John New­ton, Ol­ney Hymns (Lon­don: W. Ol­i­ver, 1779)

Its a really old hym (18th century). I think the first popular recording was done by a folk singer in the early 70's, either Judy Collins or Joan Baez.

John Newton wrote this hymn some time after converting to Christianity in the village of Kineton, in Warwickshire, England. The lyrics are based on his reflections on an Old Testament text he was preparing to preach on, adding his perspective about his own conversion while on his slave ship, the Greyhound, in 1748.

The melody most often used for this hymn was not original (nor was Newton a composer). As with other hymns of this period, the words were sung to a number of tunes before and after they first became linked to the now familiar variant of the tune New Britain of which the composer is unknown and is in William Walker's shape-note tunebook Southern Harmony, 1835.

So basically it was John Newton that was the first singer.
