[Stevie
may have said this as a joke, but frankly I can't even imagine her joking about maybe opening for Janis more than once. That's not like her at all. Evenly playfully, she would not suggest that she was even really doing drugs back when they opened for Janis. She remembers would joke about how much she remembers from those days -- which is why some of her song intros are so long -- not how little]

"We were a good band. We opened for Jimi and Janis and CCR ... I'm told we opened for Janis more than once, but I can't remember." — Fleetwood Mac's Stevie Nicks at Xcel Energy Center in January
