Unfortunately, there is very little available online about the show. No video footage. There is, however, this ad:
It only aired once, and apparently couldn't find an audience, so it wasn't rerun. For the life of me, I still can't figure out why H-B was dealing exclusively with NBC on their live-action projects. Legends was clearly on the wrong night and channel, for example, and ABC might've been able to do something with Sgt. TK Yu.
Johnny Yune passed away 8 days ago at 84 due to complications from dementia.
