Ozzy’s version sounds more polished, is a touch slower, and has the boner-inducing guitar work of Zakk Wylde.
Motörhead’s version – predictably – sounds louder, and thanks to Lem’s enormous bass sound feels more like a punch in the face. And the stomach. And the groin.
For us Rock Trivia nerds, it’s worth noting that this is the first song that Mikkey Dee recorded with Motörhead before he officially joined the band.
