who sang when the saints come marching in
"When the Saints Go Marching In", often referred to as "The Saints", is a Black Spiritual. 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).
