I remember watching this show also as a kid. I was saddened that they didn't continue it at the time. I too have been waiting/looking for it to show up on TV Land or something eventually, but it hasn't. I think TV LAnd should run it some Saturday or Sunday in the future as an all day marathon type thing. After 40+ years, I'd like to see it again myself. I found it quite funny & it had some good actors of the day portraying the astronauts and the cave man clan. Plus all the dinosaurs & volcanoes always kept my interests as a young person in 2nd grade. This, just like Gilligans Island never ran enough episodes. They were good shows to a person of THIS generation, that maybe the OLDER generations didn't like. You know, the Sinatra, Gary Cooper, & John Wayne generation. I do suppose it was cornball/stupid to those folks, but to a kid like me, I waited for it to come on each and every week.
