Sir Harry and Tina Brown are the closest thing the New York scene has to a royal couple. (Tina is Tina, and Harry is more charming and also better-looking than HRH Prince Charles of Edinburg.) On Sunday, aboard the Manhattan-sized cruise ship the Queen Mary II, they hosted a luncheon to benefit the American Institute for Stuttering. (Their son George for many years had a severe stutter.) Katie Couric was the M.C. Carly Simon was an honoree. Jack Welch sat in turtle-like repose as did, closer to the back, a very disengaged former gossip columnist Lloyd Grove. Candace Bushnell promised to set me up on a blind date and despite the early call to port—11 a.m.!—the champagne flowed freely. Joshua, still recovering from the BBQ festival avant-hier biked to Red Hook, following the limousines to the Cruise Terminal. Photographer Nikola Tamindzic took a cab.
