The lights grow brighter as the earth lurches away from the sun, and now the orchestra is playing yellow cocktail music, and the opera of voices pitches a key higher. Laughter is easier minute by minute, spilled with prodigality, tipped out at a cheerful word. The groups change more swiftly, swell with new arrivals, dissolve and form in the same breath; already there are wanderers, confident girls who weave here and there among the stouter and more stable, become for a sharp, joyous moment the centre of a group, and then, excited with triumph, glide on through the sea-change of faces and voices and colour under the constantly changing light.
Fitzgerald’s description rings true enough to transport us back to the roaring twenties.
Suddenly one of these gypsies, in trembling opal, seizes a cocktail out of the air, dumps it down for courage and, moving her hands like Frisco, dances out alone on the canvas platform. A momentary hush; the orchestra leader varies his rhythm obligingly for her, and there is a burst of chatter as the erroneous news goes around that she is Gilda Gray’s understudy from the Follies. The party has begun.
 F. Scott Fitzgerald, The Great Gatsby (1925; Hertfordshire, 1923), 27.
