The World of Commander McBragg

The World of Commander McBragg was one of several minor segments of Tennesee Tuxedo & His Tales, a Saturday morning half-hour that debuted September 28, 1963, on CBS. The producer was Leonardo Productions, which had been called Total Television before re-naming itself after its first big-name toon, King Leonardo.

McBragg's series was one of several that appeared in rotation in the two available slots backing up the lead segment, Tennessee Tuxedo's own. Others in the rotation were The Hunter (a retread from Leonardo's show), Tooter Turtle (same), King Leonardo himself, and Klondike Kat (the only one besides McBragg who hadn't been seen before).
