Hagar and Ronnie Montrose, Chickenfoot's original RHCP drummer, Michael Anthony ... they're all Purple nuts. So is Satriani who after all saved the 93 tour of Purple when Blackmore went AWOL (Satriani got an offer as a permanent member, but wanted to plough on with his solo career). Purple even played with the idea of getting Hagar in to replace Gillan around 1989, but he was at that point of course riding high with Van Halen (Eddie being another DP fan, early Van Halen having covered both DP and Rainbow songs).
I like this version too, nice the way MA does the Gillan screams at the beginning. There is a keyboard missing that's all, even though Satch does a nice job emulating a Hammond sound and Jon Lord's solo, the song needs both: a chugging guitar (downstrokes only!) and a mighty Hammond. Lord's organ made DP the sonic monster it was and he is the reason why they never had issues replicating their studio sound live (this also having to do with the fact that DP did hardly anything in the studio they could not do live; by, say, Led Zeppelin standards all their 70ies albums were underproduced and essentially live recordings in the studio, Martin Birch's strength as a producer/engineer lay in his ability to make bands sound in the studio as they sound live, his work with DP, Rainbow, Black Sabbath, Iron Maiden and BÖC all follows that school of thought).
