It must have been in the 60’s (possibly late) or early 70’s. But it was about a clan of cavemen that somehow had gotten transferred to the present day. It seems like the theme song was something like:
It’s about time, It’s about space…
Anyone?
Also, there was a cartoon where a little boy rode on the back of his flying robot (possibly some sort of super hero?).
Anyone?
Acid flashbacks getting to you again??? 
…sorry… nothing usefull to add… just thought I’d be a smartass…

acid flash back… that would be cool. I hear you just start tripping again. I could handle that… >:)
About the boy and his robot, was that possibly Frankenstein Jr.?
Yep, Frankenstein, Jr. is it. I just returned to say I had found it at http://www.tvparty.com/sat66.html and you had already posted it. But that is it.
Thanks!
The second one you want is probably Big Guy and Rusty The Boy Robot which has had an earlier incarnation than this. I think.
Or I may be waaaaaay off.
That would be "It’s About Time" from 1966.
However, you’ve got the plotline backward.
This is clearly the show you’re thinking of, because it was best known for its theme song, as explained on this web page (which probably has some of your other old favorites.)
“Johnny Sokko and His Flying Robot” (aka “Jiyaianto robo”) from 1967. This series apparently inspired a lot of kids who wanted their own flying robots.
Wow…after preview I see you’ve gotten some other options. Let us know which is your show.
I’m waaaaay off.
In the second season of It’s About Time, didn’t the cavemen come back with the astronauts to modern day? Or maybe it was the series fanale. But I do seem to remember the cavemen coming into their future. On a personal note, I’m glad other people remember this show at all. I’ve never been able to successfully forget it, but lots of other people have, and look at me like I’m crazy when I mention it.
Not that it comes up much in general conversation, mind you.
I suppose I should be ashamed to admit that, WHEN I WAS ONLY A KID, I liked the show “It’s About Time” I remember one episode where the two astronauts found out that the cave couple that were “hosting” them weren’t married(seems the institution had been invented yet) So they tried to hold a marriage ceremony. And yes, later, they came back to their own time, along with Dad, Mom, and the two kids. (Once Mom tried “sacrificing” to the god of the garbage disposal.)
Kalessa is right. In the first season, the astronauts went back in time. In the second season, the cave people returned with them.
Saints preserve us, there were TWO SEASONS???
You know I was looking through that web site and noticed something intersting. There’s a show called “Space Kidettes” /NBC
(debut)
Children in Outer Hanna-Barbera Space.
Take a look at the picture. Does that kid not have an eerie similarity to the Great Gazoo from the Flintstones?
