The Palm Beach set has begun taking refuge on the Upper East Side as the summer season starts. At Primola, Diana Strawbridge Wister, the Campbell’s soup heiress known for keeping a particularly low profile, was spotted by social spies dining with Amy Fine Collins’mother-in-law Carol Collins, Fern Tailer, financier Jamie Figg and Barbara Cates. At a nearby table were Patricia Murray Wood Ney — the mother of Hilary Geary Ross and former Southampton Press columnist whose family established the Hamptons hamlet as a summer destination — and her husband, former Young & Rubicam CEO and ambassador Edward Ney. Clive Davis, meanwhile, sat under a framed cover of his book “The Soundtrack of My Life” before he headed to the South of France for an annual European holiday. Society bandleaders Mike Carney and Bob Hardwick were also spotted at the restaurant, along with Cristina Cuomo’s parents Ranier and Regina Greeven, real-estate developer Michael Palin and Houston socialite Podi Constantiner.
