I cannot understand those folk who don't see the revisionism Paul McCartney has been involved in over the last couple of decades. Certainly, it may be in response to those who have "sainted" John Lennon: but Macca is surely doing it, whatever the reason.
My own "Macca-bashing" is really criticism of Paul's attitude, immaturity, and petulance. It is also a take on the low standards some of his music has sunk to. But there's no need, really, to call it "bashing". It's just me talking about a man whose contribution to one of the greatest bands of all time is undeniable, but who subsequently lost the plot.
No one is above criticism. Remember that even Paul himself has passed negative comments about some of his work in the eighties!
