Very interesting story.

That is a hell of a sequence

I also smacked into Billy Connolly coming around a corner in North Beach in SF. Had a number of Robin Williams encounters like when were both at the same record store and the time I was riding with Critical Mass and we passed his house and he was watering his lawn. Tried to recruit him to the mass.

Apparently the caused some major jams in Chinatown and north beach

They didn't listen.
