I remember this show vividly from my childhood -- I was in grade school when it was on and can remember watching it every week with my parents. (I think one of the reasons I liked it was that my dad was in the Navy during WWII.) I have a vague recollection that one of the episodes featured Jackie Cooper visiting Pearl Harbor and that that show aired around December 7th. Like others who've written things here, I also remember it as a serious show (I was a serious kid) and that the theme music was very unusual.I'd love to see the entire series on DVD -- or better yet, on network TV. I keep reading that the networks have given up on Saturday evenings -- why not ditch the junk they are airing that night (nobody's watching anyway) and re-run classic series like Hennesey or The Law & Mr. Jones or The Defenders or Leslie Nielsen as the Swamp Fox (which I believe was Disney.) I think Baby Boomers would love the chance to see these "lost treasures" from the 50s and 60s again. And a whole new generation of kids would be exposed to entertaining-but-intelligent programs on network TV every Saturday night.
