"Interviewer: "Mr Armstrong, would you say your music was folk music?"
Louis Armstrong: "Sure it is. Ain't never heard a horse play it!""

Wow! Never heard that before!

Oh, alright I have heard it before - but only about 10 million times ... Just because Louis Armstrong said it(or is alleged to have said it)doesn't mean that it's not a load of meaningless, facetious, over-simplistic b****cks!
