When does Monty Python's Flying Circus return?

Monty Python's Flying Circus is a British surreal sketch comedy series. It was created by and starring Graham Chapman, John Cleese, Eric Idle, Terry Jones, Terry Palin, and Terry Gilliam. The first episode was recorded at the BBC on 7 September 1969 and premiered on 5 October on BBC1, with 45 episodes airing over four series from 1969 to 1974. A feature film adaptation of several sketches, And Now for Something Completely Different, was released in 1971.
Monty Python's Flying Circus is a sketch comedy show, though it does not adhere to any regular format. The sketches include live-action skits performed by Graham Chapman, John Cleese, Eric Idle, Terry Jones, Michael Palin, and Terry Gilliam. The show's introductory theme, which varied with each series, was also based on Gilliam's animations. The title was partly the result of the group's reputation at the BBC.
