In the glorious, never to return, innocence of the inappropriately maligned 1950's, I attended an outdoor evening event with my parents at the mammoth old Soldier's Field in Chicago. The stars for the evening were Liberace and Yma. They did not perform together. When her time came, they dimmed the lights and guys dressed as Incas brought Yma out on a platform, flanked by more faux Incas with flaming torches, and placed here on a pyramid kind of thing on which she sang her stuff. I wasn't into much music, other than Les and Mary and the Chordettes, in those days, so I can't say much to judge her performance, other than she was louder than Liberace. The Bears now play football there; such has been the decline of midwestern civilization.
