Allan Carr was known as Hollywood's premier party-thrower during the town's most hedonistic era—the cocaine-addled, sexually indulgent 1970s.

With fêtes that came to be known as the Mick Jagger/Cycle Sluts Party, the Truman Capote/Jail House Party, the Elton John/Horse Party, and the Roman Polanski/Rolodex Party, not to mention the Tommy/New York City subway premiere and the Can't Stop the Music/Lincoln Center Party, it was Carr, an obese, caftan-wearing producer—the ultimate outsider—who became the first catalyst to bring movie stars and rock stars, gays and straights, Old and New Hollywood together. Tracing Carr's excess-laden rise and tragic fall as promoter and producer of both major hits and phenomenal flops—and sparing no one along the way—Hofler provides a candid behind-the-scenes look at Hollywood's most infamous era.
