I doubt this woman will care too much if you repeat some questions she's heard before. You can frame it as confirmation if you prefer, e. g. "I understand that the band is from Detroit and you're from Ottawa. Is my information correct?" And then if she says yes (or no, or anything, really), follow up. "So, I bet you've got an interesting story about how everyone met. Care to share it?"
Answers should lead to more questions. Have your questions with you, written down so you don't forget anything.
You're going to be fine.
