"Black Magic Woman" was written by Peter Green, which first appeared as a Fleetwood Mac single in various countries in 1968, subsequently appearing on the 1969 Fleetwood Mac compilation albums English Rose (US) and The Pious Bird of Good Omen (UK), as well as Vintage Years. In various interviews, Peter Green has acknowledged that "Black Magic Woman" was influenced by ["All Your Love"](https://www.youtube.com/watch?v=eAFPgAxZGJ0), an Otis Rush song that had been recorded two years earlier by Green's former band, [John Mayall & the Bluesbreakers](https://www.youtube.com/watch?v=rUUEtCBhn_Q) (albeit with Eric Clapton, Green's predecessor, on lead guitar). Although not as popular as Santana's arrangement two years later, "Black Magic Woman" nevertheless became a fairly popular blues rock hit peaking at No. 37 in the UK Singles Chart. It was featured in Fleetwood Mac live set-lists even after Green had left the band when it was often sung by Danny Kirwan, and during concerts in the early 1970s it would form the basis for long mid-concert jams. The song has the same chord structure, guitar breaks, and even a similar melody to Green's [“I Loved Another Woman”](https://www.youtube.com/watch?v=Rdik8L_Wxx4) from the band's 1968 debut album, and may have evolved out of the earlier song.
