There's quite a well known clip of someone who saw the Lincoln assassination appearing on American TV in 1959. https://www.youtube.com/watch?v=I_iq5yzJ-Dk

I was wondering if there is any known video footage of former slaves or slave owners being interviewed? It'd certainly be interesting to see them recount their experiences (especially if it were on an equally bizarre setting like this quiz show sponsored by a tobacco company!).
