I don't recall the network but in the 80's when I would get up at 6 to start watching Saturday morning cartoons, there would be this musical montage that would play before they started. The musical track was what I now know is Brandenburg Concerto No. 3 by Johann Sebastian Bach and it the visuals were a series of fast aerial wilderness shots: forests, mountains and I think a steam train appeared briefly. I've never been able to find it on YT or elsewhere and I'm not even sure what I should be calling it in search engines. Does anyone remember what I'm talking about and where I can see it?
