TOD: My Saturday mornings also usually started with cartoons or old "B" cowboy movies before the folks were up. There were also the cowboy shows like Buffalo Bill, Jr., Annie Oakley; Sky King (which I never much cared for).
As I got older, there were Saturday music lessons for me, my brother, and sister at Wurlizter's (or was it Willis'? Wurlizter, I'm pretty sure) Music Store. I took guitar lessons from Mr. Crady. A half hour lesson cost $2.50. Mr. Crady occasional subbed in the Ruth Lyons Band on TV's 50-50 Club (I have no idea why it was called the 50-50 Club).
My father usually took us and then went down the block to his office at Shillito's where he worked as an architect for Federated Department Stores. He either would meet us at the end of the lessons or we would go down to Shillito's and met him there. That way I got to look through the record department.
Once home, we had lunch and all watched the Bugs Bunny Cartoon Show. My father watched with us. After lunch, the local station channel 9 used to run a Tarzan movie, which I watched religiously. And I usually watched whatever movie they ran after that. It was those Saturday afternoons that got me hooked on old movies from the thirties and forties.
I have only one vivid memory of going to a triple feature kiddie matinee on Saturday...with cartoons and what-not. It was at the Hiland Theatre in the center of town in Fort Thomas, Kentucky, and the bill was Tarzan the Ape-man with my now-pal Denny Miller, Sabu and the Magic Ring, and Tarzan's Greatest Adventure with Gordon Scott.
