It ain't over yet,
@Forostar !
Looks like my original hypothesis was correct, someone at Toshiba just transferred master tapes to CDs without any intervention on the tracking part.
Which leaves us in a dead alley really, the word "Phatoor" came from Maiden or studio affiliates so it could be an internal joke which we will never deduce.
Next time there's an Q&A or interview, and someone from this board participates, they should really pop the question. It's a very, very obscure piece of Maiden trivia.
