The ritual of the Legacy Robe takes place on opening night on the stage of every Broadway musical that has a chorus. It began in 1950 when Bill Bradley, in the chorus of Gentlemen Prefer Blondes, persuaded Florence Baum, a chorus member, to let him have her dressing gown. As a lark, he sent it to a friend, Arthur Partington, in the chorus of Call Me Madam, on opening night, telling him it had been worn by all the Ziegfeld beauties. Arthur added a rose from Ethel Merman's gown and sent it to a chorus member on the next opening night of Guys and Dolls. It was then passed from show to show in a haphazard way and was often presented to a friend of the previous recipient, or awarded to a chorus member based on popularity. Through the years the passing of the Robe became a specific ceremony with official rules stating how it is presented, worn and paraded on stage.
