"Neon Knights" is a song with lyrics by Ronnie James Dio and music by Dio, Tony Iommi, Bill Ward and Geezer Butler. It is the first track from their landmark Heaven and Hell
album. Although Butler is credited on the album with co-writing all the songs, this is the only one with definite input by him. Butler shared in the book Precious Metal: Decibel Presents the Stories Behind 25 Extreme Metal Masterpieces
: "About three or four songs into it [the album], I had some traumatic personal problems back in England and, on top of the change with Ozzy [leaving], I had to get out of there to clear my mind. So I went back to England for a few months."
