Johnny Sokko is a great show. it's missing a legit DVD release over here, and MGM could do it up right. they were going to offer it for a burn on demand, but it hasn't happened yet. bootlegs abound though, and you can buy the whole series on itunes, which is cool.
I only ever saw the first episode as a kid, and never knew there was a compilation feature. I did see the 8mm version for sale at K-mart back in the 70s, but since I didn't know it was Johnny Sokko, I never thought to get it.
