In an interview, Paul McCartney announced that the negotiations with Apple (and EMI in the middle) had, at least for the moment, failed.
A spokesman for EMI indicated that the two protagonists had not succeeded in finding common ground but that the Major (who has much to gain) made all efforts to bring closer their points of view.
Even though we do not know what causes the blockage, one would not be a soothsayer to include the reason of money. It is probable that Paul McCartney asked for too large an advance.
