Pi

The new album "Aerial" by Kate Bush has a song called π (Greek letter p), which is about

Sweet and gentle and sensitive man
With an obsessive nature and deep fascination for numbers
And a complete infatuation with the calculation of π...

;-)

She recites π to a large number of decimal places. Actually, she doesn't recite the precise digits of π, and even omits a large block of digits, as has been noticed by many people. Now I don't believe for a minute that KB would make careless mistakes, because she has the reputation for being a bit of a perfectionist. That means that the "mistakes" in the digits are deliberate. How intriguing! This has just got to be a number puzzle that KB has set us to solve.

I don't have a solution to this puzzle. All I have done so far is to listen closely to what KB sings and how she sings it, and I have listed what I hear below.

I break up the digits into groups the same way that KB does (actually there is more structure in the way she sings the digits than I show below), I use bold font to denote digits that she particularly stresses, I put square brackets around digits that depart from the true π sequence, I use "BV" to show a contribution from the backing vocals, and I use "?" to show where I am not sure what I hear.

I have had lots of ideas on how to crack this one, but I'm not so obsessed with numbers that I am going to waste a sunny Sunday sitting at a computer working on the problem. This one gets solved in "slow time".

Has anyone got any ideas on solving this number puzzle? One idea that I reject out of hand is the suggestion that there isn't a number puzzle here!
