Louise and Len Riggio opened their Bridgehampton estate for a night of celebs, music, and Shakespeare—all to benefit the Hayground School. “The Duke, The Bard, & You” featured sounds by The Duke’s Men—former Duke Ellington band members, and a Shakespearean production by Hayground students, as guests like Roy Scheider, Art Baron, and Mercedes Ruehl dined on the Riggios’ front lawn … or should I say private park!
