The Longest Cocktail Party: An Insider's Diary of the Beatles, Their Million-dollar Apple Empire and Its Wild Rise and Fall (ISBN 1-84195-602-3) is a
rock history book by Richard DiLello, published in 1973 by
Playboy Press, and reprinted in 1981 and 2005.
The Longest Cocktail Party is one man's account of the history of
the Beatles' company
Apple Corps, the break-up of the Beatles, and the beginning of their solo careers. The title is a reference to the press office's habit of entertaining members of the media, and the company's potential business partners, with expensive drinks, luncheons and perks – which ultimately led to a financial and spiritual hangover, as did the unrealised potential of the company.
