Ragtime is the final dancing role of James Cagney.
 Ragtime was popularized during the early 20th century by composers such as Scott Joplin, James Scott and Joseph Lamb
 Irving Berlin was the most commercially successful composer of ragtime songs, and his "Alexander's Ragtime Band" (1911) was the single most widely performed and recorded piece of this sort, even though it contains virtually no ragtime syncopation
