 The play at the end of the movie was shot in a local (Toronto)  professional theater called Theatre Passe Murielle. Over four days,  many scenes from the Sound of Music were shot, including "Do, Re,  Mi", "My Favorite Things", and "The Lonely Goatherder". These scenes  were fully staged, choreographed, and costumed. Some of the costumes  came from the original Sound of Music film. In the end, almost all  of it ended up on the cutting room floor.
