OK, this is my goofiest post yet but I thought I'd ask. Has Kate Bush ever mentioned why she wrote this? The lyrics are very different from her usual material and the conspiracy theorist in me wonders if she was part of such a thing. I know little about her except I like a lot of her songs. Maybe she has a music theory or acoustics background that would qualify her? Maybe her multi-octave voice? I know the Soviets and others worked on death-sound devices so I don't think it far-fetched the Brits may have done so at some point. It's loony I know, but why not?
