Short answers, pulled from the story.
Neil Aspinall was a British music industry executive who served as road manager and personal assistant to the Beatles before becoming chief executive of their company, Apple Corps. A school friend of Paul McCartney and George Harrison, he worked with the band from the early 1960s until his retirement on the 10th of April 2007.
Aspinall met McCartney as a classmate at the Liverpool Institute on Mount Street, where they shared English and Art lessons. He met George Harrison behind the school's air-raid shelters, where Harrison asked to share a cigarette. John Lennon later joined their circle through a students coffee bar at lunchtime, while attending Liverpool College of Art nearby.
Aspinall rented a room in the Best family home and became close friends with Pete Best. While Best's stepfather was away, the nineteen-year-old Aspinall became romantically involved with Mona Best, who was seventeen years his senior. Roag Best was born in late July 1962 as a result of that relationship; Aspinall denied paternity for years before publicly acknowledging it.
Aspinall instigated three trademark suits against Apple Computer, Inc. The first, begun in 1978, settled in 1981 for £41,000. The second, filed in 1989 over the Apple IIGS synthesiser chip, settled in 1991 for £13.5 million. The third, launched in September 2003 over the iTunes Music Store and iPod, ended on the 8th of May 2006 with a ruling in Apple Computer's favour.
Aspinall played a tamboura on "Within You Without You", harmonica on "Being for the Benefit of Mr. Kite!", some percussion on "Magical Mystery Tour", and sang on the chorus of "Yellow Submarine".
Aspinall left nearly seven million pounds in his will, held in a trust with the income directed to his wife Suzy, whom he had married on the 30th of August 1968 at the Chelsea Register Office. He died of lung cancer in New York City in 2008 and was buried at Teddington Cemetery.
