I was only about five years old when I watched this show. Mark Wilson was the epitome of a magician to me. My memories of this show are a bit hazy, but I seem to remember an audience of kids watching Mark and his lovely wife, Nani Darnell, perform their act.
This was before magic became such an adult, Vegas-type attraction (and before magicians started revealing the secrets of how their tricks were done). Mark Wilson is considered one of the greats, though. He would load Nani in a box and stick swords through it. He would suspend her in mid-air and pass hoops around her.
I remember Rebo the Clown (Bev Bergeron) as looking like the clown on the box for ice cream cone cups.
The show must have had some connection with Hannah-Barbera, as there were cartoon spots shown on it. In particular, I remember a "Pixie and Dixie" cartoon on one of the Alakazam shows I watched. I guess it kept kids watching.
I really enjoyed this show. There was something happening all the time that kept your interest. Mark Wilson seemed very friendly to kids.
