Glad to find (http://Oscars.org/oscars/ceremonies) which has photo and video clips of Oscar acceptance speeches covering 8 decades.
One video clip new to me was John Wayne accepting the Oscar for an absent Gary Cooper for HIGH NOON. The Duke joked,
“I’m gonna find out why I didn’t get High Noon instead of Cooper!”
This from the man who joined Howard Hawks in denigrating High Noon.
Writer/producer of High Noon, Carl Foreman left Hollywood immediately after completing the film. He knew he would be blacklisted by the House Un-American Activities Committee.
