The sixth series of the British Sitcom series 'Allo 'Allo! contains eight episodes which first aired between 2 September and 21 October 1989.
Series 6 and subsequent episodes were 30 minutes in length, as they were not co-commissioned for the American market (as series 5 was). Jack Haig was originally meant to star in the series; but his death before the start of production prevented this. As the LeClerc character was important to the series, Derek Royle was brought in to play the part of Ernest LeClerc, Roger's brother. Naturally, the two characters are very similar in the roles that they play within the show's plot. The show also features the last appearance of Gavin Richards as Bertorelli who would be recast by Roger Kitter and Ernest would later be recast by Robin Parkinson.
The following episode names are the ones found on the British R2 DVDs with alternate region titles given below them.
René informs the audience that the café has a new pianist, Ernest LeClerc who is the brother of Roger LeClerc. When Ernest was in prison, he and Roger switched places, because, as Roger explained, the prison food was better than madame Edith's. Thus, Ernest has now taken Roger's place in the café. After he has recapitulated the events of his own death and his now posing as his twin brothers, he is about to put some flowers on his "brother's" grave. Both Yvette and Edith join him in the café, but they both decline the offer to come with him to the graveyard. Yvette asks him to place a cactus (which resembles a penis) on the grave for her, and Edith gives him a rhubarb (which has gone stale and therefore cannot be sold to any customers) to be placed there. René is not very fond of either idea, but they are soon interrupted, when Mimi tells them they are wanted in the backroom by Michelle of the Resistance.
Michelle informs them that beneath René's brother's "grave", the Resistance are building a communication centre, with a wireless radio, because the one in madame Fanny's bedroom is being jammed by the Germans. Secondly, they need a bigger aerial to be able to contact London and tell them when to put the next escape plan for the British airmen into action. The radio will be ready within the next 24 hours and because they will go there when it is ready, under the pretence of putting flowers on René's brother's grave, they must not go yet.
