Interesting to see the full 90 minutes of the Gene Autry Western tribute. I've only ever seen bits on Youtube before. I am not sure there is any other footage of Wayne and Ford together being themselves. Curious how much Wayne stands behind Ford, not pushing in, unlike Ward Bond, who Ford hastily pushes to one side. Also interesting how much Ford touches Wayne, puts a hand on his shoulder, leg. Very Possessive body language.
I never saw the ending before but in the mock fight with James Arness and the stuntman, you can see Duke crash in and "win" the fight, while everyone around starts laughing. As it was filmed live it looks like it was not planned and Wayne was having fun.
