Somebody markets a cassette tape of these girls from the old Ralston/Purina radio show. Do any of you "Caters know of a source of that tape? Or any other recording format. This tape has a number of songs on it. It is not the best tape in the world, since many of the songs and intros to the songs are a bit clipped, but it still is a fantastic tape. Those girls sure could yodel! I'm trying to find this for a friend, and any help you can give would be most appreciated. Thanks.
