Peter Green's Fleetwood Mac (sometimes also called the Original Fleetwood Mac) is not to be confused with the more famous Fleetwood Mac of the mid to late seventies, which featured Lindsay Buckingham, Stevie Nicks, and Christine McVie. All that remained in that group of the original British Blues outfit of a decade earlier was the rhythm section of John McVie and Mick Fleetwood, from which pair all incarnations of the band derived the name.
