From The Beatles
author Hunter Davies in The Guardian:
He was with them through all their years of fame. He would get shouted at, told to fetch impossible things, fix ludicrous arrangements. In 1968, Paul decided on the spur of the moment to come and visit me in Portugal with his new girlfriend Linda, and her daughter Heather. Neil was told to get them on a plane to Faro. The last flight had gone. So, late at night, Neil secured a private jet and off they went.
But Neil was more than a roadie and fixer - he was their friend and confidant, helped with words of songs when they got stuck, with personal relationships when they wanted them unstuck.
His accountancy training proved invaluable when he came to run Apple. As the years went on, he masterminded much of the group's professional affairs and back catalogues. On the whole, Neil won most of the battles, helping them make further millions. He did also have a creative streak, acting as the producer of the film Let it Be and organising the Beatles Anthology.
Neil was totally loyal and faithful to them - and yet not at all starstruck. He was more than aware of their foibles, greed, stupidities, unreasonableness, would readily slag them off. It was clear he was part of the family, so while moaning, as all family members do, he would never betray their secrets.
When I pressed him for inside stories, he used to say he couldn't remember. Mick Jagger always says the same. In Neil's case, it could be because he wasn't really much interested in the personal stuff. His mind didn't quite work that way. He had a dry, austere, rather resigned, cynical view of most people, more interested in facts and figures than tittle tattle. He was there, but was somehow floating above it all. The Beatles were very fortunate to have him.
