The song begins with a keyboard solo by Don Airey. "I just cleared [the band] out of the studio and said, 'Come back in half an hour,'" he recalled. "Ozzy came back, heard it, and said, 'You just plugged into my head, man.'"[3]
The first guitar solo by Randy Rhoads became one of the best known in heavy metal. It was ranked 28th best guitar solo by the readers of Guitar World in 2011.[4] The song was ranked the 23rd greatest heavy metal song of all time, according to a poll by Gibson.[5]
The official guide to the video game Fallout 3 uses the lyrics to the song in its walkthrough of You Gotta Shoot 'em in the Head.[6] The game also features a ghoul character named "Mister Crowley".
This song was also featured in the game Brütal Legend.
The song was included in Guitar Hero World Tour, along with "Crazy Train" and an in-game avatar of Ozzy himself, who becomes unlocked as a playable character upon completing both songs in the vocalist career, and was made available to download on 31 May 2011 for play in the Rock Band 3 music gaming platform in both Basic rhythm, and PRO mode.[7]
On Ozzy Osbourne's 'Hellraiser (30th Anniversary Edition - Official Animated Video)' video, the legend "Mr. Crowley" appears on the sides of the van.
