Seems to me there's yodeling, and then there's yodeling. At one end of the spectrum you have some guy in lederhosen yodeling at 90 miles an hour to a tour busload of overweight middle-aged Americans trying to have an Authentic German Experience. Here I agree with Harald and Wolfgang. But at the other extreme, you have the slow, mournful, sublime Blue Yodels of Jimmie Rodgers. That's a horse of a different feather.
