1976 outdoor footage on "Two Sticks..."

i know i won't get a lot of replies to this but i need to ask anyway...

David, i know you probably know this so help!
Where and when was that footage filmed on the "Two Sticks and a Drum" doc? Clips have also been shown on the "Going Home" doc. There's a real quick clip at the beginning of the program ("Two Sticks...") of the outside of the stadium with a name on it but i can't quite make it out. Just curious. I have no idea where it was filmed but i know it's got to be from 1976. ???
