In the late eighties in Denver I got front row seats to a comedy extravaganza, that included many of the best comics in the business, including Louie Anderson and Robin Williams. I was stunned by Robin William’s brilliance. No one could touch him at improv. Improv, whether it be comedy, words or music demands that you open to forces that are utterly inspirational, and very demanding. He had the magic. That night I had an invite to a poker game with the comics. I was teaching at UC Boulder and I was already jet lagged from a trip to Central America, and worried about being able to teach my classes the next morning, so I turned it down. There you have it: one of my biggest regrets. We have lost a major cultural light. RIP Robin Williams.
