The cast of characters includes Andy, Liza, Halston, and Bianca--no last names needed--and other luminaries etched into Steve Rubell and Ian Schrager's exclusive guest list. The anecdotes include lurid details of the revelry and stories like the one about that Halloween when two Lady Godivas were kept outside but their horse was allowed in. Haden-Guest resists the obvious urge to dish too much about the stars and instead examines the club as a social phenomenon. In his book, the front door of Studio 54 swings open just long enough to let escape the shadow of a scene that's long since seen the light of day.
