where can I find old classic footage of red carpet / emmy/ oscar??

I was thinking, I love movies / tv. But I would love to see it from 40's/50's+. Anyone know where I can see for example, new (young) Jack Nicholson, Warren Beatty, Shirley McClaine, Lucy & Desi, Vivian Vance, Joan Crawford, Natalie Wood, Liz Taylor, Bette Davis...etc. ALL the classic stars from that era, at Red Carpet / emmy / oscars ??

I would imagine a lot of this stuff is on youtube.

Here's one of Bette Davis & Spencer Tracy accepting their Oscars for "Jezebel" and "Boys Town":
