Mikhail Gorbachev's speech to the NPRA Luncheon on Tuesday, in the Ballroom of the main conference hotel, the new Grand Hyatt, was attended by around 600 delegates.
I wasn't there myself but I was leaving for the airport just as everyone was piling in to the hotel for the 11 am start to the lunch event. It was the busiest I had seen the lobby all conference.
I crossed the road with my friend Kevin, who said that he saw Mr Gorbachev in the hotel that morning, and went up and shook his hand and gave him a business card.
"You never know when he might want to buy some benzene," said Kevin hopefully.
Press delegates to the conference were allowed in to sit at the back of the room after the lunch had been served and cameras were strictly forbidden.
Delegates commented that the speech was vague on specifics and not helped by Gorbachev speaking over the translator.
I was sorry to miss it. Two of the recent NPRA Luncheon speakers - Gen Colin Powell and John Major - were really excellent.
