This was an early appearance of many actors and comedians who were to become more famous later: [David Jason]?, [Denise Coffey]?, [Graham Chapman]?, [Eric Idle]?, John Cleese and others. The Bonzo Dog Doo-Dah Band performed a song in each programme. The programme was a series of sketches, often bizarre and surrealistic, frequently satirical, a style which was to become more famous with the later appearance of several cast members in Monty Python's Flying Circus: at least one sketch was reused in the Python series. Strange animations between sketches were supplied by the then unknown Terry Gilliam, who also graduated to Python - his `christmas cards' animation reappearing there.
One long running spoof was Captain Fantastic, a highly improbable superhero and his even more improbable adventures.
