The radio was a big part of my childhood. At school we had a big speaker in the corner of every classroom. This was for announcements, but also for the ABC radio shows that were part of the curriculum, and some that were just for entertainment.
The youngest kids, when I was in primary school, were called "bubs", and in bubs' grade we had a radio story at nap time, Mitten the Kitten. He was always in trouble. The show started with him singing "I'm Mitten the kitten, the kitten with the mitten, I'm Mitten the kitten, yo ho." Not exactly top ten material.
For the "health" subject, we had Peter and Wendy Martin. They were two kids who taught us about things like basic hygiene, sound nutrition, and getting exercise, but the episode I remember the most was the one where they exercised their skeptical muscles. One of the twins had woken un and was afraid because they thought there was a ghost in the bedroom. The other one talked them through the experience and they realised it was not a ghost at all, just a jacket hanging on the back of the door.
We had the music show with June Epstein on Tuesday afternoons, with a work book that had all of the songs in it.
At home, my favourite radio spot was just a little five-minute segment on the breakfast show, it was The Adventures of Smocker the Cat. I listened to that show for years and even got a copy of the book. Years later, I got the meet Ross Higgins, who had been the voice of Nasty Neighbour Norton, Smocker's sworn enemy. Even though it had been years since Smocker had been on the radio, Ross was instantly able to recreate Norton's voice for me.
