@Tbeaton,
My brother and I were on that show in 1973. Basically, our social worker was interviewed by the host and talked about us while we played on the floor in front of them. The reason I know this, is after we were adopted, we happened to see the re-run of our show!!!
Funny, I work with a girl now who's family was looking to adopt, and they used to watch the show as well. We are from southwestern Ontario.
