I was lucky to see the late Yma Sumac perform in 1975; she kindly autographed the program booklets for fans after the show. (Inside, it says that her wardrobe was designed by Lloyd Lambert "from Hollywood and Las Vegas.") In addition to her famed multi-octave voice, she had a great sense of humor, too. During the encore she collided with a curtain that started to draw in for the close, but kept right on vocalizing!
UPDATE: Gregg Nystrom just sent along a picture of his Yma Sumac paper doll--she's a knock-out!
