Heard some odd things about Kate Bush recently. Seemingly she is trying to block a public right of way and a beach in Devon, where she has a second home, and is so obsessed with her privacy she even went up in a helicopter to see if people were looking into her garden.
I wouldn't say she's obsessed with her privacy, per se, she just wants to lead a completely normal life and raise her son. I don't think she's trying to block access to the beach, but she does want the existing right-of-way diverted so it doesn't go straight past the house. It's odd because you'd really have to want to badly find that house, because it's pretty hard to just stumble across it by accident. It's away from other houses and quite a way down a dead-end lane on a headland. A stalker did actually break into the house a few years back, but luckily she wasn't staying there at the time.
