Pi (update 3)
When I haven't been filling myself with mince pies and mulled wine, I have been writing up my analysis of Kate Bush's song π (Greek letter p) which I described earlier here, here, and here.
There is quite a lot of material, so I have organised it as a web site called A Great Big Circle.
I have actually got quite a bit further with decoding this song than I have described on the web site, but I will need to do some "field work" to sanity-check the various ideas that I have had. Conveniently, the field work can be combined with a holiday in a very nice area of the country (i.e. the Land's End area, Cornwall).
With what I have discovered thus far, I know for certain that Kate lavishes attention on every detail of her published music, and that even things that appear to be sloppy errors (e.g. out-of-tune notes, or clumsy lyrics) are actually deliberate.
