By the time Radiohead began their first US tour in early 1993, their debut single "Creep" had become a hit. Tensions were high, as the band felt smothered by the success and mounting expectations. Following a gruelling tour, they cancelled an appearance at Reading Festival after Yorke became ill; he told "NME", "Physically I'm completely fucked and mentally I've had enough." According to some reports, Radiohead's record company EMI gave them six months to "get sorted" or be dropped. A&R head Keith Wozencroft denied this, saying: "Experimental rock music was getting played and had commercial potential. People voice different paranoias, but for the label were developing brilliantly from "Pablo Honey"."
