I saw Peter Green at one of the first of his 'comeback' gigs back in the 1980's, and interviewed him afterwards for a guitar magazine.
He played BMW, of course, and when the roof was duly raised, he smiled and advised that he didn't know there were so many Santana fans in the room!
I have always adored the Santana version because Santana Abraxas was the very first album I bought, and played it to death, and it remains one of my fave albums ever.
Mr Green was very modest, I tried to assure him that he was a guitar hero to millions, and he refused to have it, not out of the typical annoying faux modesty that English people have drilled into them as children, but because he genuinely felt he didn't deserve that level of adoration.
Of course, if you can write songs like Black Magic Woman, then you do deserve it - and he does!!
