Classical, European folk evolved into country and rock came from parts of Europe including England. Jazz is American, and much of the world from Copenhagen to Paris to Japan embraces American Jazz, especially from Scott Joplin through the Be Bop era. Some of the best American Jazz I was able to ever see was at Jazz bars in Kovenhavn at 3 in the morning. New York City is sometimes referred to as the city that never sleeps, Kovenhavn seriously does not sleep. Even the hot dog vendors on the street are out in the "wee" hours.
