The title is "London Calling", but according to Guy Siner the first lyrics are:  Carmen Silvera sang the full song and it was released on LP in the 1980s. The café cabaret music usually took the form of 1930s film and show tunes – reminiscent of the way period songs were also used in "Secret Army". Most popular was "Louise" from the film "Innocents of Paris" (1929), which featured a number of times and was even sung in the "broken-French" language of Crabtree, who pronounced the title "Loo-woes". Gruber sang a number such as "Can't Help Lovin' Dat Man" from "Show Boat" or "(I Got a Woman Crazy for Me) She's Funny That Way" by Neil Monet and Richard A. Whiting. He gazed at René in a slightly lustful manner, replacing lyrics such as "woman" and "she" with "boy" and "he". He caused a particular sensation with his straight version of Noël Coward's "Mad About the Boy". Naturally the "La Marseillaise" and the German National Anthem "Deutschlandlied" featured from time to time, for example where several French peasants sang La Marsellaise to celebrate the expected bombing of the Germans, but the singers flawlessly and without hesitation switch to Das Lied der Deutschen when the Germans come past. Helga also sometimes stripped to a rather raunchy version of the latter tune. Captain Bertorelli could be seen singing "'O Sole Mio (It's Now or Never)"; and the British airmen in a prisoner of war camp could be seen singing "Hitler Has Only Got One Ball". In 1986, Gorden Kaye and Vicki Michelle released a version of the hit song "Je t'aime... moi non-plus". The characters of Yvette and René could be heard talking and canoodling in a comic manner whilst the familiar musical "Je t'aime..."' melody played in the background. The song got to number fifty-seven in the UK Singles Chart. In 1985, Gordon Kaye and Carmen Silvera appeared in the Royal Variety Performance in character as René and Edith, and sang "I Remember It Well" (from "Gigi". The show gave rise to a successful touring stage-show featuring most of the TV cast. This ran from 1986 to 1992, and included three London stage runs as well as international tours.
