In 1967 Peter Green, Mick Fleetwood and John McVie played in the legendary John Mayall & The Blues Breakers, and were given free studio time during which they recorded five songs. Peter Green was so convinced of this band's musical prowess that he formed it on the spot and named it after the drummer & the bass player. John McVie, however, wasn't convinced yet, and it forced Fleetwood Mac to find a temporary replacement in Bob Burning.
