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 wasn't convinced & it forced Fleetwood Mac to find a temporary replacement in Bob Burning. After a short while, however, he was as hooked on the Elmore James influenced British Blues that he left John Mayall to take a risk on a group of unknowns. The rest is history.
