It was 44 years ago this week, on June 26, 1970, that the Pythons started recording the second series of Monty Python’s Flying Circus.

The Pythons shot most of their film segments during the summer, so that when they went into the BBC studios to tape the programs before an audience, the outside segments could be shown to an audience and edited in afterward. And that is why, when John Cleese walks along the street, walking silly, he changes from film to tape when he walks onto the studio set.
