In 1839, the Tyrolese Minstrels toured the United States and started an American craze for Alpine music. During the 1840s, dozens of German, Swiss, and Austrian singing groups crisscrossed the country entertaining audiences with a combination of singing, yodeling, and "Alpine harmony." The popularity of the European groups led to the formation of many American family singing groups as well. The most popular was the Hutchison Family Singers who toured, singing harmony and yodeling. Minstrel shows parodied the Hutchison's yodeling with their own, calling it "Tyrolesian business". In 1853, Christy's Minstrels burlesqued (parodied) the Hutchinson Family singing 'We Come From the Hills With Tyrolean Echo'.
