Who borrowed it? Zappa or Santana?
Santana.
In fact, Santana has said that he was greatly inspired by early Peter Green stuff like 'I Loved Another Woman' (the chords are great) and 'Supernatural'. Of course, one of Santana's biggest early hits was the Peter Green song, 'Black Magic Woman'.
(In case anybody is unfamiliar with Peter Green, he was the guitar player who took Eric Clapton's place in John Mayall's Bluesbreakers after Clapton left to form Cream. While with the Bluesbreakers, Green wrote a song called 'Fleetwood Mac', as a tribute to the Bluesbreakers' bass player, John McVie, and a sit-in drummer named Mick Fleetwood. Peter Green later started his own band and took the bass player and the drummer with him. He added a friend, guitar player Jeremy Spencer, and named his new band Fleetwood Mac, after his song.)
