I too remember seeing the Mavis Bramston show. Mavis was not actually a character at all, although her image in black skirt and large black hat appeared from time to time. It was actually a bit "naughty" in our household, so as an early High school student it was special to see it. My favourite was the "second best friend". Sadly the march of technology destroyed it: The show was made in the early/mid 60s when 2 inch video ("Quad" technology) was king. Unfortunately the tape didn't last and the machines died. (they used to weigh the head drums to check for the wear. If there was a broken head, the tape would get shredded!) If it was made a bit earlier it would have been on film or at least kinescope and still be with us.
