John Graham McVie is a British bass guitarist. He is best known as a member of the rock bands John Mayall& the Bluesbreakers from 1964 to 1967 and Fleetwood Mac since 1967. His surname, combined with that of drummer Mick Fleetwood, was the source for the band's name. He joined Fleetwood Mac shortly after its formation by guitarist Peter Green in 1967, replacing temporary bass guitarist Bob Brunning.
