Earl Carroll's first attempt at a "book" musical. At the time, the most expensive flop in history, costing his backer, Mrs. Anne Weightman Penfield $350,000. Carroll cast his girlfriend, Dorothy Knapp, as the star even though she couldn't sing. Knapp did not sing at all and was panned by the critics.
