What I have to say about Macca, in short, is that the "cute" Beatle in real life is not exactly "cute." Sir Paul {Oh, that 'Sir' bit makes me gag!} has become a bit of a monster: "The Great Walking Ego."
He was arrogant, turning up late for the meeting with Brian Epstein that would seal their future, and soon considered himself a cut above the others.
Macca really broke up The Beatles. He was the first one to sue. He hated that the other three wanted Allen Klein to be their manager - he wanted the Eastman family to represent them, Linda's family - so he simply sued for dissolution of "Beatles Inc."
Macca drove Wings to a very bitchy end. He mis-treated his bandmates, insisting on having his own way over every note, every single stage movement, even every stage costume. He was notorious for not paying the band on time, or in amounts of $$ promised, or not paying at all. (He refused to sign contracts establishing exact remuneration band members would be paid.) He played favourites with pay packages, creating an atmosphere of sycophancy: Be nice to Himself, maybe you'll get paid more than the others.
He has recorded so many desultory, awful solo albums that went nowhere, unlike his fellow Beatles who usually at least got their records on the charts. (Even Ringo)
He has hidden behind a carefully cultivated PR image of blokeish normality, but ultimately his phalanx of PR hacks fail to disguise a man who has lost touch with everyday reality, buying land, houses, cars and horses as we shop for groceries. A music-business manager is quoted in "Fab": rock stars are never like the rest of us - they only pretend to be.

It's clearly evident that Macca has one MASSIVE EGO, and he's a Control Freak! He is, however, a talented actor and uses his personal charm to seduce "friends" and fans. I think his seductive charm - his charisma - was the quality of his that first pulled him into John Lennon's orbit. Didn't Lennon sour on him after many years, saying that Paul was a person he loved-and-hated? There you have it: Macca is a "difficult" personality. Yes, he's hugely talented, ambitious and charismatic. But everywhere he goes he tends to leave a few enemies behind. It's so easy for fans to raise a talent like Macca to god-like status. But he's just a human being. Not much different from you, or me! His knighthood is no big deal - everybody and his brother in the UK gets one for doing anything impressive. His vast wealth allows him to insulate himself from the real world, our world where people have to give a bit to take a bit, and get along with one another. No, he Gets Everything He Wants! Not so Cute!
