Black Sabbath are a famous metal and rock band formed in Birmingham, England, in 1968. Still performing over 40 years later, the band members became known for their numbers (approx. 36) and multiple collaborations, leading musical links to the band to become the third and final component of the Erdős-Bacon-Sabbath number.
Despite the fame of some band members, including Ozzy Osbourne, Tony Iommi, Geezer Butler and Bill Ward, no members of Black Sabbath have a verified Erdős-Bacon-Sabbath number.
