This well-known song probably originated as a 19th-century African American hymn. It became hugely popular in the 1930s, and soon was a standard for not just black gospel singers and congregations but in churches all over the US south. It has been performed in every style of country music, as well as by brass bands and, especially, New Orleans jazz musicians, who play it at funerals. This arrangement is not very difficult and depends very much on the useful trick of fretting with the thumb.
