I've been reading a biography of Richard Pryor titled Furious Cool: Richard Pryor and the World That Made Him. It's a fascinating book, but one excerpt in particular reminded me that the 1960s were an amazing, amazing time.
The author noted that Buck Henry recalled that in 1963 in Greenwich Village, it was possible to see all of the following comedians in the same night, all performing within a few blocks of each other: Lenny Bruce, Richard Pryor, George Carlin, and Woody Allen.
This is a tremendous piece of work, by the way. I had no idea of the crazy dimensions of Pryor's life, much of which couldn't have happened in any other era.
