Fleetwood Mac were Brit-rock stalwarts when, in 1974, they hit on the idea of pepping up their lineup. They invited a folky Californian, Lindsey Buckingham, to join, but he refused to come without his girlfriend, Stevie Nicks. The band agreed, on one condition: their sole female member, Christine McVie, had to feel comfortable with Nicks.
They met over dinner in Los Angeles, and McVie, finding Nicks “funny and nice, but also, there was no competition”, waved her through. That decision led to the enlarged band becoming the sultans of soft rock, underlining McVie’s status as the quiet pillar of the Mac apparatus. (And she was right; Nicks complemented rather than competed. She was the ethereal conjuror, McVie the “very, very, very English” – in Nicks’s appraisal – countermeasure, and neither ever upstaged the other.)
