Question: How many total album sales were made between the 1978 Who album that Bundrick was invited to play on and the 1981 album that he was featured on? Passage 1:The book discusses four prehistoric migrations in India. The book mentions that the Harappans were a mixture of Zagros agriculturists and First Indians, a wave of migrants who came from Africa into Arabia and then reached India around 65,000 years ago. Citing recent DNA evidence, the book traces the subsequent large migrations of anatomically modern humans into India—of agriculturalists from Iran between 7000 and 3000 BCE and Indo-European languages speaking pastoralists from the Central Asian Steppe (Aryans) between 2000 and 1000 BCE, among others. Tony Joseph used pizza as a metaphor to explain the break-up of subcontinental society. The book also discusses about similarities and differences between Indus Valley civilization and early Vedic civilization. The book mentions that ‘Aryan’ culture was most likely the result of interaction, adoption and adaptation among those who brought Indo-European languages to India and those who were already well-settled inhabitants of the region, and that Sanskrit and Vedas developed in the Indian subcontinent. Various tribes like the Andamanese and the Semang (Malay Peninsula), the Mani (Thailand) and the Aeta people (the Philippines) were the earliest inhabitants of Southeast Asia. According to Joseph, Proto-Dravidian is related to the Elamitic language of Iran. Caste system in India is a recent social system, reflected in sharply reduced inter-marriage (endogamy) and genetic mixing after 100 AD. This book also takes into account the path-breaking DNA research and findings from geneticist David Reich's research.
 Passage 2:Hardy cites Sting, The Ultimate Warrior, and Shawn Michaels as his childhood inspirations to wrestle. He started on World Wrestling Federation (WWF) television as a jobber—a wrestler who consistently loses to make his opponents look stronger. His first WWF match was against Razor Ramon on May 23, 1994 in Youngstown, Ohio, with Randy Savage mentioning on commentary, "Welcome to the big time". His ringname that night, Keith Davis, was the name of Razor's scheduled jobber, who backed out on short notice. Gary Sabaugh, who had brought Hardy in a group along with Davis, suggested him to agent Tony Garea, who agreed after Hardy claimed he was 18 (he was in fact, only 16). The next day, he wrestled under his real name against The 1–2–3 Kid, and the match aired on the June 25 episode of Superstars. He occasionally wrestled as a jobber as late as 1997 (including a match against Rob Van Dam during the ECW "invasion" storyline that had Hardy billed as being from Virginia instead of Cameron, North Carolina) before beginning his first major run in 1998.
 Passage 3:Bundrick first worked with Pete Townshend in 1977 when he performed on Rough Mix, Townshend's solo collaboration with Ronnie Lane, former bass player for Small Faces and Faces. He was invited to play on the Who's album Who Are You (1978), but broke his arm falling out of a taxi at the studio door and was unable to participate in recording sessions. Bundrick toured with The Who from 1979 to 1981 along with drummer Kenney Jones and played on their album Face Dances (1981), then briefly parted with the band during the recording of It's Hard (1982) and the subsequent tour. Bundrick later rejoined the band performing with them at Live Aid in 1985 and played live with them until 2012.
