The film's final scene is wholly inaccurate; there was no performance by E.P. Christy on the day that Foster died. In reality, Christy actually died nearly two years before Foster; he committed suicide by throwing himself from a window at his home in New York City in May 1862; Foster himself died in January 1864.
In this movie, Stephen Foster marries a girl from the South, but in real life, his wife was from Pittsburgh.
