“I have failed utterly to find anybody referencing any such incident in the immediate aftermath of the show”

Self styled siren:

And by “immediate aftermath,” I mean from Monday, March 28, 1973, until about February 1974. In addition to what could be found on the internet, Professor Thomas Doherty of Brandeis University graciously offered to access the relevant issues of The Hollywood Reporter, which are not online. Nothing about Wayne. THR, then staunchly right-wing, ran an editorial by Tichi Wilkerson Miles, scolding Brando. There was also a roundup of quotations from various figures. In the approving camp was Alfred Ruddy, Godfather producer; opting for the diplomatic route of “well, you know, artists” was the legendary Robert Evans of Paramount; disapproving, not of Littlefeather but Brando, were Academy president Daniel Taradesh, Michael Caine, and Charlton Heston. And at the end of the THR roundup, a brief interview with Littlefeather herself, with a truly lovely vignette: “She noted that ‘a very nice man,’ Eddie Albert, and his son Edward Albert, congratulated her on her remarks and said they supported what she did.” 

No word from John Wayne. His response to the whole affair didn’t come until Dec. 30, 1973, in an interview in the New York Times

What about that other big kid —Marlon Brando? Does Duke—an Academy Award winner for “True Grit”—look upon Brando’s nixing of his Oscar for “The Godfather” as a mature action, or mere kid stuff?

“You’re going to take this out of context, aren’t you?” Duke squints, and then breaks into a who-gives-a-damn grin. “I think it was sad that Brando did what he did. If he had something to say, he should have appeared that night and stated his views instead of taking some little unknown girl and dressing her up in an Indian outfit.”

When does the Wayne story start showing up? Leaping ahead a bit, there is a 1988 interview with Marty Pasetta, the director of the Oscar show from 1972 to 1988, a stretch of time that in retrospect looks like the Oscar show’s Golden Age. Of that night in 1973, Pasetta told Ivor Davis:

“We had a fight is what we had,” recalls the silver-haired Oscar veteran… “John Wayne wanted to go out there and physically yank her off the stage. It took six men to hold him back.”

Bingo! Right?

Well, hold the phone. There are significant problems with accepting Pasetta’s 1988 recollection at face value (and that is why I am calling Snopes sloppy).
