Technical Ecstasy. The music itself was less dark and more atypical than that of previous albums, especially on the ballads "It's Alright" and "She's Gone". The ballad "It's Alright" was written and sung by drummer Bill Ward. Initially reluctant to sing the song for fear of offending Osbourne, he was encouraged by the band to do it. In his autobiography, Osbourne praises the performance, enthusing, "He's got a great voice, Bill, and I was more than happy for him to do the honours." It was released as a single because, said Iommi, "We want to break out as far as we can… so we've decided to hit the singles market." It has since been covered live by Guns N' Roses, and was included on their Live Era '87–'93 album. It was also featured in the 2010 film It's Kind of a Funny Story.

Anyway, it's love at first sight, but I felt robots wouldn't do it like humans would do it, so instead they're squirting lubricating fluid at one another." The UK release had a two-sided insert of lyrics and credits. Tour During the subsequent 1977 European tour in support of Technical Ecstasy, the band was supported by AC/DC. The relationship between bassist Geezer Butler and AC/DC rhythm guitarist Malcolm Young was quite tense. Guitarist Tony Iommi recalls the atmosphere between the two being "heavy" and that the pair did not get along at all. 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
