Big Blue Marble - intro

Big Blue Marble was a children's television program that aired from 1974-1983. Each episode contained 2 or 3 different segments, each one focusing on a child from a different country (what their life was like, interests, etc...). The apparent goal of the program was to promote cultural awareness/understanding. I believe themes like ecology were also discussed.
The show encouraged viewers to become "pen pals" with other viewers from different parts of the world, and facilitated this with a segment during each show.
As far as I know, the show hasn't been shown (at least in the US) since it originally aired. I've heard that some of the children that became pen pals kept in touch for years (even to present day).
This version of the show's intro was from a later season and is a different song than was originally used*. I don't know when the change was made but both seem to be remembered fondly depending on when you watched. You can hear the melody of the original song sung faintly at the start of this clip.

Cultural understanding: that's the 70's for ya. Should kids today be exposed to stuff like that?
