Here are some of the coolest I watched:
1968 Oscars: Humanitarian Award to Martha Raye
Bob Hope (who was not hosting that year) comes out and does a little comedy bit before giving an honorary Oscar to his former radio & film co-star Marta Raye, honored for her service in Vietnam.
After a comedy bit by Oscar co-host Robin Williams, Quincy Jones comes onstage to give an honorary Oscar to Alex North, who was nominated for 15 Oscars but never won. One of his nominated scores was for "Who's Afraid of Virginia Wolf?", which I have some issues with because there is very little music in the film.
In his speech, he makes a plea for Hollywood to have less gratuitous sex and violence in movies, which is followed by applause, interestingly.
1938 Oscars: Bette Davis, Spencer Tracy and Deanna Durbin winning Oscars
From February 23, 1939. Newsreel footage from the Oscar ceremony. This is a treat! Rare, hard to find footage!!
Thank you, Oscars, for uploading these gems!
