In the introduction to the Barnes & Noble version of Peter Pan, Amy Billone writes,
"When Peter endeavors to save Tinker Bell's life, he shouts to the audience, 'Do you believe in fairies? If you believe, wave your handkerchiefs and clap your hands!' Because Barrie was convinced that the play would be a disaster and that this line would be greeted with silence from the stylish adult audience, he had arranged with the musical director to have the orchestra put down their instruments and clap. As it turned out, when Nina Bouciault asked if anyone believed in fairies, the audience applauded so enthusiastically that she burst into tears. (xxi)"
