It was Jones who was the driving force behind abandoning punch lines at the end of sketches and developing what became the show's trademark stream of consciousness.
This also took a lot of pressure off the writers, who no longer had to dream up a killer line to round off a sketch.
Graham Chapman would appear as an army colonel and declare the sketch over because it was "too silly". Alternatively an armoured knight would wander on and hit someone over the head with a rubber chicken.
Jones also appeared naked, apart from a collar and tie, playing an organ as a form of punctuation between sketches.
He made something of a speciality of playing middle-aged women, often one of the screeching harridans that populated the show.
Possibly his most memorable appearance was in The Meaning of Life as the exploding Mr Creosote who, after a gargantuan feast, misguidedly accepted "just one wafer thin mint"
