Thanks for this. Wow, I remember seeing this off a film projector in Ontario Elementary School, sometime between the mid-to-late 70s A good film for the time. I remember all the ambulances sounded like that, but then a somewhat different 2-tone sound came in by about the late 70s. One thing for sure, fewer people had knowledge of first aid back then, and without cell phones . . just look how long it took the woman in the station wagon to get to a phone booth. My mother was a nurse in those years and she would sometimes ride down to Toronto with critical patients (in those very types of ambulances) if the patient needed more critical treatment or advanced care in one of Toronto's bigger hospitals. I never thought I would see this again . . . I never forgot seeing this film, so many years ago!
