During the subsequent 1977 European tour in support of ''Technical Ecstasy'', the band was supported by [[AC/DC]].<ref name="iommiautobiography" /> The relationship between bassist [[Geezer Butler]] and [[AC/DC]] rhythm guitarist [[Malcolm Young]] was quite tense.<ref name="iommiautobiography" /> Guitarist [[Tony Iommi]] recalls the atmosphere between the two being "heavy" and that the pair did not get along at all.<ref name="iommiautobiography" /> Ward's drum tech Graham Wright and Osbourne's personal assistant David Tangye stated in their 2004 book ''How Black Was Our Sabbath'' that the problems between the two originated after a show the two bands performed earlier in [[Switzerland]].<ref name="howblack">{{cite book |last1=Tangye |first1=Dave |last2=Wright |first2=Graham |title=How Black Was Our Sabbath |year=2004 |publisher=PAN Macmillan Adult |isbn=978-0-33041-1943 |page=193}}</ref> An altercation occurred in an hotel bar in which Butler removed a switch-blade comb from his pocket and opened it. Young thought it was a [[Switchblade|switchblade knife]] and believed Butler was pointing it at him.<ref name="howblack" /> In the [[Bon Scott]] biography ''[[Highway To Hell]]: The Life and Times of AC/DC Legend Bon Scott'', [[Clinton Walker]] writes of the tour: "Sabbath, by 1976, were well past their prime, and AC/DC were all but blowing them right off the stage. Substance abuse in the band was rampant." Graham and Tangye also disclose that during the tour drummer Ward had begun driving from gig to gig in a rented [[Winnebago Industries|Winnebago]] due to a fear of flying.

Osbourne briefly left following the [[Technical Ecstasy Tour]]. Although he would eventually return for the follow-up ''[[Never Say Die!]]'', the band temporarily replaced him with former [[Savoy Brown]] vocalist [[Dave Walker]]. The band wrote a handful of songs with Walker, and performed an early version of what would become "Junior's Eyes" on the [[BBC]] programme ''Look Hear'' with him.
