Their end needs to wire up the auditorium they're going to use (um...it had not occurred to me until today that most of what the audience sees will be my head. My giant head, floating there on the big screen, like something out of a horror movie, detached from all else. Why didn't this happen when I was 40 years younger and looked it??? Oh, well. I'm the one who asked about doing this.)
I'm assured that the two techs involved today are indeed going to be the two techs involved on the day.
I've done television interviews, where I had no live audience to play off of, but most of the time--at colleges or conventions--I'm right there with people. I'm hoping my energy sustains the same way when I'm looking at a monitor. Maybe extra dark chocolate that morning....
