This, to me, looks like Christine pressed the wrong button. She doesn't look like she's playing, right? I think she was looking for help...like "oh crap, what happened? what'd I do" It's probably pre-recorded, the intro (or the entire part). And she counts off for the entire crew. Hmmm, this is interesting. Could explain why Christine was so nervous in 1997, and now they have technology to make her feel better on stage?
