The original version of the song appeared on Big Star's 1972 debut album # 1 Record. In 2000, Chilton confirmed that he was paid $70 in royalties each time the show aired, an amount he thought ironic, given the show's title.

Question: Based on this passage, who wrote the theme song for that 70's show?
