I realize that probably no one but Paul himself knows the exact answer to this question, but I was wondering what you all think about how much recorded material Paul might have around that hasn't been heard by the public.This question occurred to me because I was recently reading that he recorded 7 or 8 songs for his High in the Clouds project, and as far as I know these haven't been heard. Also, the McCartney 3 song When Winter Comes was apparently recorded back in the 90's, so while it obviously got released eventually, it apparently sat around unheard for a long time.How much unheard material do you all think Paul has "in the vault"? It seems to me like he must have built up a lot over the years, and I'd be very curious to know what he has.
