Monkey Business is the most thorough and fully researched biography of all five Marx Brothers -- Chico, Harpo, Groucho, Gummo and Zeppo. It features the first true account of their origins, their comedy roots, and their twenty-four years on stage prior to their movie career. Louvish brings to life the vanished world of America's variety circuits, leading to the brothers' Broadway success and their alliance with George S. Kaufman and The Algonquin Round Table. Never-before-published scripts, Marxian dialogue, and much madness and mayhem feature in this tale of the brothers' Hollywood battles, their lives and loves, and the politics of Marxism-a-la-Groucho.
