Fleetwood Mac are a British-American rock band formed in London in 1967 by guitarist and singer Peter Green. Green recruited drummer Mick Fleetwood, guitarist and singer Jeremy Spencer and bassist Bob Brunning, with John McVie replacing Brunning a few weeks after the band's first public appearance at the 1967 Reading and Leeds Festival. 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.
