There’s still time for some end of summer philanthropy! Over the weekend, the Prostate Cancer Foundation took over the Parrish Art Museum in Water Mill for a good time, and a good cause. The night featured dinner, performances, and a conversation between PCF Founder Michael Milken and Elon Musk.

Attendees included Julia Koch and her children Mary Julia and David Koch Jr., Christine and Stephen Schwarzman, Maye Musk, Neri Oxman and Bill Ackman, Mei Sze and Jeff Greene, Ginger and Larry Leeds, Fay Ann Lee and John Lloyd, Mary Ross and Leo Wagner, and Dani and Ted Virtue.
