"When the Saints Go Marching In". Often referred to as "The Saints", is an American gospel hymn. 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 song is sometimes confused with a similarly titled composition "When the Saints Are Marching In" from 1896 by Katharine Purvis (lyrics) and James Milton Black (music).
