British-American rock band formed in London in 1967 by guitarist and singer Peter Green. Green recruited drummer Mick Fleetwood, multi-instrumentalist and singer Jeremy Spencer and bassist Bob Brunning, with John McVie replacing Brunning a few weeks after their first public appearance. Guitarist and singer Danny Kirwan joined the band in 1968. Christine Perfect, who contributed as a session musician starting with the band's second album, married McVie and joined Fleetwood Mac as an official member in July 1970 on vocals and keyboards, two months after Green left the band; she became known as Christine McVie. By the end of 1974, Weston and Walker had been dismissed and Welch had left, leaving the band without a guitarist or male vocalist. While Fleetwood was scouting studios in Los Angeles, he heard the American folk-rock duo Buckingham Nicks, consisting of guitarist and singer Lindsey Buckingham and singer Stevie Nicks. In December 1974, he asked Buckingham to join Fleetwood Mac, with Buckingham agreeing on the condition that Nicks could also join. The addition of Buckingham and Nicks gave the band a more pop rock sound and their 1975 album Fleetwood Mac topped the Billboard 200 chart in the United States. The band's succeeding album Rumours (1977) produced four U.S. Top 10 singles and remained at number one on the Billboard 200 for 31 weeks. It also reached the top spot in countries around the world and won the Grammy Award for Album of the Year in 1978. Rumours has sold more than 40 million copies worldwide, making it one of the best-selling albums in history. Although each member of the band went through a breakup (John and Christine McVie, Buckingham and Nicks, and Fleetwood and his wife Jenny Boyd) while recording the album, they continued to write and record together. Fleetwood Mac have sold more than 120 million records worldwide, making them one of the world's best-selling bands. In 1979, the group were honoured with a star on the Hollywood Walk of Fame. In 1998, the band were inducted into the Rock and Roll Hall of Fame and received the Brit Award for Outstanding Contribution to Music.
