Drummer Mick Fleetwood heard some cuts from Buckingham/Nicks in '75, and, impressed, asked the duo to join Fleetwood Mac. "It's a good thing that happened right then," says Nicks. "Without Mick's offer, I think we would have had some really terrible problems. We were nothing, with no money, and suddenly we were making two hundred dollars a week each. I moved into a more expensive apartment. Lindsey moved in with me two weeks later. We'd been trying to break up, off and on, for years.
Although the strain of working in the same group took its toll on Nicks's relationship with Buckingham (they broke up for good in 1976), her songwriting began to bloom. She wrote Fleetwood hits that included "Rhiannon," "Dreams" and "Sara."
