Unknown 1972 OW/Graver shorts

[Wellesnet]

At Gary Graver's imdb page, there are 227 credits for cinematographer. In addition to all the exploitation cheapies like "Dracula vs. Frankenstein", "One Million AC/DC", and "Virgins of Sherwood Forest", there are all the works he did for Orson Welles listed too. Among these are 5 short films from 1972 that I've never heard of:

An Evening with Orson Welles: Chesterton Speeches
An Evening with Orson Welles: Clarence Darrow Speeches
An Evening with Orson Welles: Socrates Speeches
An Evening with Orson Welles: The Happy Prince
An Evening with Orson Welles: Wodehouse Speeches

I suspect this may be a hoax, or simply in error, but you never know.
