joined Green by the summer of 1967 with a record contract on the horizon. Peter Green's Fleetwood Mac The initial incarnation of Fleetwood Mac performed its first gig in August 1967 at the seventh annual Windsor Jazz and Blues Festival, playing a Chicago-style blues. McVie, initially hesitant to commit, was later prompted to leave the Bluesbreakers and join Fleetwood Mac full-time when the former adopted a horns section with which he disagreed. He replaced the initial bassist, Bob Brunning. McVie, Fleetwood, Green and guitarist Jeremy Spencer thus formed the first fixed line-up of Fleetwood Mac. The band's first album, Peter Green's Fleetwood Mac, was released in 1968, and the band toured the United States for the first time, though Green was reluctant to do so for fear of gun crime. Upon their return, they recorded a second album, Mr. Wonderful under simply "Fleetwood Mac" with Green's name dropped. A guest musician on the album, Christine Perfect, became close with the group and she and McVie were married in 1968. A third guitarist, Danny Kirwan, was also added to the line-up. Despite the success of their third album, Then Play On, and a string of hit singles including "Albatross" and "Man of the World", Green himself drifted away from the band, struggling both creatively and with increasing use of LSD. 1970–1973 Fleetwood remained a consistent presence in the ever-changing line-up of the group following the departure of Green in May 1970, when Spencer and Kirwan assumed more central roles in the group's song-writing. In September 1970 the release of Kiln House saw a line-up of Spencer, Kirwan, John McVie and Fleetwood, with Christine McVie providing keyboards and backing vocals. Fleetwood, "a social creature who prized community and communication", was particularly taken with the group's new living arrangements: they moved into a large Victoria-era mansion near Headley, Hampshire. By early 1971, with Christine McVie becoming an official member of the band, Fleetwood and the group boarded a plane to San Francisco. Spencer, fearful following the recent 1971 San Fernando earthquake, reluctantly boarded the plane. He left the hotel abruptly one afternoon and disappeared. He was found several days later to have joined Family International, then known as Children of God, a religious group. Once more, Fleetwood attempted to mediate; however, Spencer would not return. Bob Welch would become their next member. Their next album, Future Games, was released later that year. Bare
