Geoff Emerick (engineer) : I lost interest in the White Album because they were really arguing among themselves and swearing at each other. The expletives were really flying... I said to George [Martin], 'Look, I've had enough. I want to leave. I don't want to know any more.' George said, 'Well, leave at the end of the week' – I think it was a Monday or Tuesday – but I said, 'No, I want to leave now, this very minute.' And that was it.
