IT is the eye-roll that gives it away. Catty, half-impatient, delivered with the attitude and sass that only a drag queen can muster.

Once Richard Move, the male impersonator of the late great dancer Martha Graham dispenses those classier-than-thou eye-rolls, you know it's not Graham you're witnessing but a man impeccably dressed and made up to look and sound like her - never mind if he's two heads taller than the actual woman.

Graham, of course, is the mother of modern dance, having invented the angular, intense, iconoclastic style of dancing that you now see in showcases of contemporary dance everywhere in the world.
