The film started life as a part of a 90-minute TV special for CBS, entitled Orson's Bag, consisting of Welles' 40-minute condensation of The Merchant of Venice, and assorted sketches around Europe.
The film features contributions from British comedians Tim Brooke-Taylor, Graeme Garden, and Bill Oddie, before the trio became known as The Goodies.
Welles plays Winston Churchill fielding press questions and then exchanging bons mots with Nancy Astor (Oja Kodar).
The longest segment of the film (9 mins) has a bowler-hatted reporter (Tim Brooke-Taylor) wandering through "Swinging London", searching for Carnaby Street with limited success.
Most of the supporting roles are played by Welles in a variety of disguises: a British policeman, an old lady selling "dirty postcards", a Chinaman luring customers into a strip club, and the omnipresent one-man band.
The song "One Man Band" was written by Bill Oddie (who had joined Brooke-Taylor and Garden for the second season of the TV sketch series Broaden Your Mind).
This segment is noteworthy for what reviewers have called its "Pythonesque" style[1] - which is significant as it was filmed before Monty Python's Flying Circus first aired in October 1969.
[2] It is set in a London club in which Welles plays four different members, all under heavy make-up, plus a noisy waiter who drops things.
The non-London sketch segments of Orson's Bag were edited by the Munich Film Museum into the 9 minute short Vienna.
