Nicks gives them lots of advice (about journaling, songwriting and - at their request - insight into managing their burgeoning fame) and apparently gave them a little more: the opportunity to perform one of the songs she wrote for Fleetwood Mac.

"I believe that if you close your eyes and see yourself up on that stage, being bigger than life, you become that person with that big, really good attitude," Nicks told the ladies of Haim during the course of the interview. "You're gonna be that rock 'n' roll woman that's gonna make people happy and take them out of their miserable lives for two hours . . . and they're going to want your music. And then, girls . . . at 66 years old, you can be starting a year-and-a-half tour that sold out its U.S. dates - in the first week."
