Black Sabbath’s biggest international hit single (it topped the pop charts in Germany, hit #2 in Switzerland, and #4 in the UK) is also one of their shortest, coming in at less than three minutes. Geezer Butler told Guitar World that the song “was written as an afterthought. We basically needed a three-minute filler for the album, and Tony came up with the riff. I quickly did the lyrics, and Ozzy was reading them as he was singing.”
On this dark, dreary Friday…..some Sabbath is in order!
