I was lucky enough to see Elvis Presley’s final concert at Madison Square Garden in June 1972. Usually, you are not allowed to bring a camera to a concert. But the audience and the entire event were so wild that no one paid any attention to me. Over the years I watched the footage again and again. Then the Viennale called and I immediately thought of my Elvis material. The only problem was that I didn’t know what kind of musical soundtrack to use. I tried everything and was close to giving up when I happened to hear a Viennese waltz on the radio. That was it! What could be better – or funnier – than Elvis and Strauss? (Jonas Mekas)
