Fleetwood Mac are a British-American rock band formed in 1967 in London. Due to numerous line-up changes, the only original member present in the band is its eponymous drummer, Mick Fleetwood. Despite band founder Peter Green naming the group by combining the surnames of two of his former bandmates (Fleetwood, McVie) from John Mayall's Bluesbreakers, bassist John McVie played neither on their first single nor at their first concerts. The keyboardist, Christine McVie, who joined the band in 1970 while married to John McVie, appeared on all but two albums, either as a member or as a session musician. She also supplied the artwork for the album Kiln House.
