Impossible to have a celebration and ignore the events of the day, so one of the guests played and sang Amazing Grace - very moving.
RIP the innocent victims of Columbine.
I just remember walking out of a seminar into the hotel lobby, and seeing it on the tv screen there...within two minutes there was a large crowd of watching and waiting for word as to what was actually happening. It was surreal standing next to a Mossad agent and a Brit counter terrorism expert and just listening to their running commentary.
