All right, here's a couple that I think are regional as well as old, so I don't know if anyone will recognize them. Anyway, here are some more kiddie shows from my youth in the NYC area:
Magic GardenThis first one is Magic Garden. This show stopped in the '70's, so clearly it's being re-run given the G rating at the start of the video. I totally loved this show as a small child.
Kids Are People TooThis was the offspring of Wonderama. It may have been national, but I believe it came out of Baltimore.
I couldn't find a Romper Room that looked familiar to me, sigh.
There was also a regional PBS show that had a man with a mustache reading childrens stories as an older woman drew with pastels to illustrate the story. The theme was I think "Take Five" by Dave Brubeck, or a different Brubeck song. It was definately Brubeck, though. It would have either come out of NYC, Philly, Boston or Chicago. I wish I could remember the name, I watched that show religiously.
