"Amazing Grace" is a Christian hymn published in 1779 with words written in 1772 by English Anglican clergyman and poet John Newton (1725–1807). It is an immensely popular hymn, particularly in the United States, where it is used for both religious and secular purposes.

Newton wrote the words from personal experience; he grew up without any particular religious conviction, but his life's path was formed by a variety of twists and coincidences that were often put into motion by others' reactions to what they took as his recalcitrant insubordination. He was pressed (navally conscripted) into service with the Royal Navy, and after leaving the service, he became involved in the Atlantic slave trade. In 1748, a violent storm battered his vessel off the coast of County Donegal, Ireland, so severely that he called out to God for mercy. While this moment marked his spiritual conversion, he continued slave trading until 1754 or 1755, when he ended his seafaring altogether. Newton began studying Christian theology and later became an abolitionist.
In 1972, the Royal Scots Dragoon Guards, the senior Scottish regiment of the British Army, recorded an instrumental version featuring a bagpipe soloist accompanied by a pipe band. The tempo of their arrangement was slowed to allow for the bagpipes, but it was based on Collins's: it began with a bagpipe solo introduction similar to her lone voice, then it was accompanied by the band of bagpipes and horns, whereas in her version she is backed up by a chorus. It became an international hit, spending five weeks at number-one in the UK Singles Chart,[78] topping the RPM national singles chart in Canada for three weeks,[79] and also peaking at number 11 on the Billboard Hot 100 in the US.[80][81] It is also a controversial instrumental, as it combined pipes with a military band. The Pipe Major of the Royal Scots Dragoon Guards was summoned to Edinburgh Castle and chastised for demeaning the bagpipes.[82]

Aretha Franklin and Rod Stewart also recorded "Amazing Grace" around the same time, and both of their renditions were popular.[i] All four versions were marketed to distinct types of audiences, thereby assuring its place as a pop song.[83] Johnny Cash recorded it on his 1975 album Sings Precious Memories, dedicating it to his older brother Jack, who had been killed in a mill accident when they were boys in Dyess, Arkansas. Cash and his family sang it to themselves while they worked in the cotton fields following Jack's death. Cash often included the song when he toured prisons, saying "For the three minutes that song is going on, everybody is free. It just frees the spirit and frees the person."[3]

The U.S. Library of Congress has a collection of 3,000 versions of and songs inspired by "Amazing Grace", some of which were first-time recordings by folklorists Alan and John Lomax, a father and son team who in 1932 travelled thousands of miles across the southern states of the US to capture the different regional styles
