New York Times:

In 1986, Robin Williams was at a crossroads. “Mork & Mindy” was four years behind him, and his movie career had been foundering. His marriage to Valerie Velardi, his first wife and the mother of their son, Zak, was unraveling. But he still had two reliable sources of joy in his life: his live comedy act, and Zak.

Zak was just 3 at the time, but in his own way, he played a pivotal role in Robin’s stand-up tour from this period, which culminated in a performance at the Metropolitan Opera House.

Over the span of this hour-long set (which was also released as the Grammy Award-winning comedy album “A Night at the Met”), he plays his usual grab-bag’s worth of characters: Robin Leach, Ronald Reagan, a ballet-dancing Tom Landry and, in a whispery, falsetto voice, Zak.

I was/am a huge fan of Robin Williams. I first met him here in Vancouver while he was shooting Jumanji and I interviewed him in San Francisco at a Macworld Expo. We corresponded for a time and I treasured the little piece of him I had. I remember this bit well and this is a great dissection of it.
