NO! Thank you for telling us. It was on MSNBC that I heard the applause later as the motorcade left the funeral home. ABC radio news reporter said applause had broken out when Nancy arrived, but I had Fox on and hadn't heard it. I think you're right about the microphones NBC must have set up there.
The crowd applauded when the coffin appeared, and again when Nancy got into the limo to go. She looked touched and waved.
