David Geffen is the money man behind Crosby, Stills and Nash, Guns N' Roses, Cher, Shrek, Gladiator, and even Cats the musical. Journalist Zing Tsjeng and BBC business editor Simon Jack tell the remarkable story of the Brooklyn boy who conquered Hollywood and became an entertainment mogul. From starting in a New York agency mailroom to the heart of Laurel Canyon’s hippie-rock scene, David Geffen rubbed shoulders with almost every major cultural figure of the 20th century. Joni Mitchel wrote a song about him, and Cher dated him. Then he moved from the music industry to movies, founding DreamWorks with Steven Spielberg and building one of the world’s most valuable art collections.
