I am sitting in a Pink Floyd-themed bar different from the one you are in now. I am recording the sound of the Tina Turner concert DVD and I am going to play it back into the bar again and again until the resonant frequencies of Tina reinforce themselves so that any semblance of her speech, with perhaps the exception of rhythm, is destroyed. What the others will hear, then, are the natural resonant frequencies of the bar articulated by pop music. I regard this activity not so much as a demonstration of a physical fact, but more as a way to smooth out the wrinkles in my brain.
