An early member of Fleetwood Mac, slide guitarist Jeremy Spencer left behind a fine (if limited) musical legacy, but is perhaps better remembered for his sudden defection from the group to join a religious cult. Spencer was born in West Hartlepool, England on July 4, 1948; he started taking piano lessons at age nine, switched to guitar at 15 to emulate his rock & roll idols, and the following year discovered Elmore James, who became his chief influence. In 1967, Spencer became the fourth member of the fledgling Fleetwood Mac, concentrating primarily on slide guitar but also doubling up on piano. He was a major component of the group's early blues-rock sound on albums like 1968's Peter Green's Fleetwood Mac and 1969's English Rose. A gifted musical impressionist, Spencer's affectionate send-ups of early rock & roll styles and artists were sometimes incorporated into the group's live shows; in 1970, Spencer released a self-titled solo LP in that vein on Reprise, featuring parodies of rockabilly, teen idol ballads, surf, Elvis, psychedelia, and even Mac itself. That same year's Kiln House would prove to be the last Mac album Spencer played on, however. ~portion of bio by Steve Huey.

Jeremy Cedric Spencer (British; aliases used include Jonadab and Jonathan, though he now goes by Jeremy again) was born in West Hartlepool, England on July 4, 1948. Spencer was one of Fleetwood Mac's early guitarists, joining the band in 1967. His specialty was the slide guitar and he was strongly influenced by blues musician Elmore James. Spencer remained with the band until February 1971 when he joined the Children of God, upon which he renounced his possessions and cut his long hair.

He remains with The Family International (as the group is now called) to this day, participating in missionary activities, performing in studio recordings for the group (primarily in Brazil), and illustrating Family publications for children. Spencer now lives in Ireland and works mainly as a book illustrator and story writer for The Family International.

Spencer performed in concert tours in India with other Family International performers in 1995, 1998 and 2000. Shortly before the start of his 1998 tour, Fleetwood Mac performers including Jeremy Spencer were inducted into the Rock and Roll Hall of Fame.
