Here's a pretty interesting
video of the Montys Python, where they appeared in an interview on the Dallas PBS station that aired the first episodes of Monty Python's Flying Circus in the U.S. It was filmed in 1975, I think, before Holy Grail was even released in theatres, and they talk a bit about the show and censorship in Britain and a stuffed armadillo. The most interesting thing to me is how obviously completely wasted Graham Chapman is. His alcoholism eventually killed him in 1989.
