Cecile and Ezra Zilkha's table sat such as the French Ambassador to the U.S. and Mme. Jacques Andreani, who was not to be missed in a black Cardin with winglike white sleeves big enough to outfit a band of angels; the French Consul General and Mme. Andrea Baeyens; Astrid and Kip Forbes; Jerry Zipkin, and the Donald Zilkhas (it was his birthday). And scattered throughout the stage were Mary and Mike Wallace, the Joseph Volpes, the Edmund Pillsburys, Lucile and Guy Peyrelongue, Anna Moffo, Helen Gurley Brown and David Brown, Chris and Bruce Crawford, Lady Fairfax, the James Kinnears, Mrs. Gilbert Humphrey, etc., etc., etc. But more of all this frenzy on Friday when the Bass love-in continues and Prince and Princess Michael of Kent are given send-offs in Palm Beach by Emelia and Pepe Fanjul and in New York by Lee Thaw.
