From the wiki: “‘When the Saints Go Marching In’, often referred to as ‘The Saints’, is an American gospel hymn. According to jazz critic Al Rose this tune was first published as a Baptist hymn in 1916 and credited to Edward Boatner, the man behind religious-classic ‘He’s Got The Whole World In His Hands’. Though it originated as a Christian hymn, it is often played by jazz bands. This song was famously recorded on May 13, 1938 by Louis Armstrong and his Orchestra.
“The first known recorded version was in 1923 by the Paramount Jubilee Singers on Paramount 12073. Although the title given on the label is ‘When All the Saints Come Marching In’, the group sings the modern lyrics beginning with “When the saints go marching in”. No author is shown on the label. The earliest versions were slow and stately, but as time passed the recordings became more rhythmic. Louis Armstrong was one of the first to make the tune into a nationally known Pop tune in the 1930s. (Armstrong wrote that his sister told him she thought the secular performance style of the traditional church tune was inappropriate and irreligious.)
