Lead Singer Change: Bob Welch to Stevie Nicks/Lindsey Buckingham/Christine McVieFleetwood Mac went through more than its fair share of lineup changes throughout the '60s and '70s. In 1971, Bob Welch joined the band as a vocalist and guitarist, but the era of Welch was short-lived. When Lindsey Buckingham was asked to join in '74, he made sure his girlfriend (Stevie Nicks) could come along for the ride—and that's when Fleetwood Mac started seeing mainstream success.
