 This might explain why the city in which the film is set, and by extension Stokowski's "regular" orchestra, is never positively identified in the film.The music was recorded in multi-channel stereophonic sound but released in monaural sound; three years later Stokowski and the Philadelphia Orchestra appeared in the first feature film to be presented in stereo, "Fantasia".Jane Barlow, ballerina and a student of Nijinska, was a body double for Deanna Durbin in this film.
