2018-08: Livro de Womack fala de amuo de George Martin

... durante as gravações do White AlbumGeorge Martin Was ‘Frozen Out’ of Beatles’ White Album Sessions 

Citando:
"Womack said he’d spoken to sound engineers and tape operators for his book Sound Pictures: The Life of Beatles Producer George Martin, the Later Years, 1966–2016. “I asked them what George was doing when John [Lennon] was playing a particular guitar part or when Ringo [Starr] was working on some drum part,” Womack told the Guardian. “They would say, ‘Nothing, he was in the back of the booth, reading newspapers, sharing his chocolate with us.’ He was on a kind of a chocolate-and-newspaper strike.”

The author said that, along with the Epstein tragedy, the falling-out “also had a lot to do with a Time magazine article in 1967 where George was credited with being this wunderkind and the mastermind behind Sgt Pepper. “They didn’t take very well to that and let him know,” Womack added. “I do think this was the beginning of this struggle over ‘Who’s the genius behind the Beatles?’ This was payback for taking credit for the Beatles myth. … But they coaxed him back for Abbey Road [in 1969].”
