Sheet Music, The Twentieth Century Rag

Description:

Sixteenth century Protestant European scholars introduced the practice of describing past times in hundred-year intervals known as centuries and used it to group events together chronologically. By the twentieth century, this practice had been adopted in popular song. "The 20^th Century Rag" had words by Grant Clarke and Edgar Leslie, with music by Maurice Abrahams.
