Barbra arrived, stood on the platform. She said something along the lines of "thank you all for coming out tonight. I hope you feel you got you money's worth". Then she left. From start to finish it seemed like 30 seconds (at the most, 45 seconds). That's my perception of the encounter. I know others who were there posted she was there longer, but if felt like 30 seconds. I also don't remember verbatim what she said, so if anyone was there and wants to add to her speech, please feel free to do so. There is probably a video out there of the whole event. I just remember it was very short and then it was over.
