It was during the Munich years, too, that Hitler first began to conclude his speeches by leading his audiences in a rousing and angry chant. A confidant from those years, Ernst Hanfstaengl, had gone to Harvard, and been impressed with the fight songs used at football games. With Hanfstaengl's guidance, "Fight, Harvard, Fight" thus became "Sieg…Heil! Sieg…Heil! Sieg…Heil!…Heil Hitler!"
