Of course a recording done nearly thirty years later can give no true indication of the massive emotion that the speech created, which the narrator hints at. Paul F. Boller Jr. in his book "Presidential Anecdotes" describes the scene;
Bryan's "Cross of Gold" speech touched off a demonstration lasting close to an hour,during which delegates shouted, cheered, and wept. carried Bryan around on their shoulders in triumph and waved banners on which were scribbled "No crown of thorns No cross of gold"

As Lincoln took the stage that evening at Cooper Union, he faced an audience of 1,500 spectators. Most of them were active in the Republican Party, and among them were such luminaries as the editor of the antislavery New York Tribune, Horace Greeley.
