"The show featured Jones and Ustinov as themselves in a car in London perpetually searching for Copthorne Avenue.
The comedy derived from the characters they met along the way, often also played by themselves.
The show was unusual for the time in that it was largely improvised with the tape subsequently edited for broadcast by Frank Muir and Denis Norden, who also sometimes took part.
Two of the more popular characters were Morris and Dudley Grosvenor, two rather stupid East End spivs whose sketches always ended with the phrase ""Run for it Dudley"" (or Morry as appropriate)."
