The group was formed by four teenage friends from Aston, near Birmingham, England: Anthony "Tony" Iommi (b. Feb 19, 1948), guitar; William "Bill" Ward (b. May 5, 1948), drums; John "Ozzy" Osbourne (b. Dec 3, 1948), vocals; and Terence "Geezer" Butler (b. Jul 17, 1949), bass. They originally called their jazz-blues band Polka Tulk, later renaming themselves Earth, and they played extensively in Europe. In early 1969, they decided to change their name again when they found that they were being mistaken for another group called Earth. Butler had written a song that took its title from a novel by occult writer Dennis Wheatley, Black Sabbath, and the group adopted it as their name as well. As they attracted attention for their live performances, record labels showed interest, and they were signed to Phillips Records in 1969. In January 1970, the Phillips subsidiary Fontana released their debut single, "Evil Woman (Don't Play Your Games With Me)," a cover of a song that had just become a U.S. hit for Crow; it did not chart. The following month, a different Phillips subsidiary, Vertigo, released Black Sabbath's self-titled debut album, which reached the U.K. Top Ten. Though it was a less immediate success in the U.S. -- where the band's recordings were licensed to Warner Bros. Records and appeared in May 1970 -- the LP broke into the American charts in August, reaching the Top 40, remaining in the charts over a year, and selling a million copies.
