People may not know Aspinall by name, but he basically kept The Beatles organization running from the late 60s, through all the crazy lawsuits and changes in the industry and technology, all the way to last year when he resigned as the head of Apple.
An Associated Press article said:
A Liverpool school chum of McCartney and Harrison, Aspinall was The Beatles' first road manager and would drive them to gigs in his van. He later became their personal assistant, and in 1968 was given a management role at Apple Records, the band's own record label.
As head of Apple Corps, Aspinall was executive producer of the hugely successful "Beatles Anthology" album and was behind other successes, including the "Beatles One" album.
"As a loyal friend, confidant and chief executive, Neil's trusting stewardship and guidance has left a far-reaching legacy for generations to come," the band's statement said.
