Two of my most vivid memories from the concert (other than Nina's performance itself) are of a woman rushing up to the stage while Nina was standing at the front of the stage . She reached up to Nina and Nina bent down and kind of shook the woman's hand. Security quickly came out and shooed the woman away but I could see her walking back up the aisle to her seat just staring at her own hand as if in disbelief that she had actually touched Nina Simone. I clearly remember thinking that I completely understood and I would have also been in disbelief if I had touched Nina as well.
The other memory is Nina asking us in the audience what song we wanted her to perform. A lot of people shouted their requests and when there was a lull in shouts I very loudly yelled "Be My Husband!!!!" to which Nina gave a kind of "ohhhhhhh" and a chuckle, which at the time I took as her indicating that she wasn't up to doing that song (no piano playing, heavy on the percussion...I think it would've been difficult to perform on a whim for her at her age at the time). Now I'm not even sure if she was actually responding to my request but at the time I was over the moon believing that she had not only heard me but had responded to me.
