I'd have to say I'm sceptical about the Kate Bush pic as well- been reading quite a bit about her recently, and apparently the famous Gered Mankowitz 'pink leotard' pics where her nipples were very evident didn't go down well with the Bush family, and there were arguments with EMI over the pics being used to promote 'Wuthering Heights' and her first album. In one of the pieces I've read, her brothers in particular are described as 'The mafia! the bruvvers!....
Very protective of their little sister'
Against that background, I find it hard to believe anyone getting Kate to take her top off for the camera....
