I didn't watch a lot of "children's" shows shows per se; mostly cartoons and, like Druxy, cowboy shows. The local kiddie host in the Cincinnati area, Uncle Al, just passed away a couple of weeks ago. He was something of an icon with his straw boater, red and white striped coat, and accordian. He was part of the WLW/Taft Broadcasting that went beyond local to regional and, I believe, Uncle Al went national for a year or so.
My other favourite kiddie host was Bob Shreve, who used to bring us Popeye cartoons and Three Stooges shorts, but didn't really come into his iconic loopy crazy genius until he started hosting the Schoenling Beer All-Nite Theatre. It was a wild and funny show. He was sort of our local Soupy Sales.
Elmore, do you remember any of these characters?
