I've Got a Secret with guests John Cale and Karl Schenzer (1963)

From the YouTuber who uploaded this gem:

"John Cale was the guest on this September 16, 1963 episode of I've Got a Secret. His secret centered around his participation in an 18 hour piano playing marathon that was the first full length performance of Erik Satie's "Vexations". (Not mentioned, John Cage was also one of the pianists.) Also on stage was Off- Broadway actor, Karl Schenzer, who's secret was that he was the only person to stay for the entire concert performance."

Dick Gregory: State of the Black Union (2008)

In the stand-up comedy world, a comedian works hard to make their carefully scripted material seem spontaneous. Make no mistake about it, Dick Gregory sat down and wrote all of this material - and then rewrote it - until it was perfectly crafted. It may seem off-the-cuff, but the legendary Dick Gregory is doing much of his stand-up act in this appearance at The State of the Black Union that happened the other day. And he destroyed.
