I'm doing research for a novel that partly incorporates ExtraTERRORestrial Alien Encounter, though not by actually being there. (When I went on it in 8th grade, during an end-of-the-year trip to the Magic Kingdom, it scared the s... out of me (I was uneasy about going on it with my group, but agreed, though still was nervous), but over the years, I've grown to respect its flawless storytelling.) Some of that research is about the attraction itself, namely the costs, but also about Jeffrey Jones as Chairman Clench.
This forum indicates that Chairman Clench appeared in the preshow for Invasion! An ExtraTERRORestrial Alien Encounter at DisneyQuest:

But that's not all I'm looking for. First, for those who went there, how long was the preshow, and do you remember exactly what Clench said? Was it only about "how happy the company was for this opportun, uh, responsibility, to help the people of Earth."?
Thanks for any assistance you can provide.
