was having dinner at a Kings Cross restaurant Sugarmill in 2011 (I had a tip-off)..Robin Williams came in with Elijah Wood. They had been nearby recording voice-overs for Happy Feet 2.
Robin gave an impromptu performance for 40 minutes- I'm sure he would have gone for hours unless stopped. Surely one of the funniest comedians alive with a machine gun delivery once he started.
His press conferences were always packed for the same reason.
very sad
