Editing Joyce Grenfell (section)

===Post-war work ===
Back in London Grenfell wrote the song "Du Maurier" (music by Addinsell) and the monologue "Travelling Broadens the Mind", both of which she performed in [[Noël Coward]]'s first post-war revue, ''[[Sigh No More (musical)|Sigh No More]]'' (1945).<ref>Mander and Mitchenson, pp. 378 and 380</ref> Coward had been a family friend since Grenfell was a girl.<ref>Grenfell (1976), p. 81</ref> At first he had viewed her transition from amateur to professional with some doubt.<ref>Hampton (2002), p. 124</ref> Within a few years he had come to recognise her professionalism, her skill as a performer ("good in all she does on the stage") and the quality of her monologues, even if "she shouldn't write lyrics."<ref>Coward, p. 35</ref> In addition to her own two numbers, she sang Coward's comic catalogue of domestic disasters "That is the End of the News", "disguised as a schoolgirl with pigtails, all my make-up off, a shiny face and a terrible grin."<ref>Castle, p. 189</ref>

After the 1947 revue ''Tuppence Coloured'', Grenfell developed new sketches including the first of her six Nursery School monologues, with the harassed teacher's recurring cry to one of her unseen charges, "George – don't do that...."<ref>Hampton, pp. 65 and 182</ref> In the 1951 revue ''Penny Plain'' she performed her "Joyful Noise" (music by [[Donald Swann]]), a parody of an amateur choir ("And some of us cannot sing much, And some can't sing at all, But how we love our outings to the Royal Albert Hall").<ref>Grenfell (1984), p. 74</ref> After this, Grenfell and Tunnard made another tour entertaining British troops in North Africa.<ref name=h342>Hampton (2002), p. 342</ref>

''Joyce Grenfell Requests the Pleasure'' (1954) was her first more or less solo West End show (there were three dancers providing interludes between Grenfell's numbers).<ref name=cam>"Cambridge Premiere", ''The Stage'', 29 April 1954, p. 10</ref> ''The Stage'' commented that any doubts that Grenfell could sustain a solo evening were quickly dispelled:
{{blockindent|Miss Grenfell satirises, gently but inevitably, 20 different women, including the earnest but misguided devotee of health through rhythm, the arty curiosity-shop owner, the offhand sales-girl, the mercenary writer of children's stories (a gem, this!), the Victorian hostess whose husband had left her, the humourless American discoverer of folk songs of many lands, the shrinking but eager girl at the local palais, the incompetent but ardent Scottish dancer, the modern miss, and the Swedish visitor at a cocktail party.<ref name=cam/>|}}
After two provincial tours and a year in London she took the show to [[Broadway theatre|Broadway]], where it had a sell-out eight-week run.<ref name=h97/> For this show there was a [[pit orchestra|pit band]] of eight players directed by [[William Blezard]]. In later shows Grenfell simplified the format further, dispensing with dancers and band, and being accompanied only by Blezard at the piano.<ref name=h97>Hampton (2003), p. 97</ref>

During the 1950s and 1960s Grenfell appeared in several film roles including "Lovely Ducks", the shooting gallery attendant in  ''[[Stage Fright (1950 film)|Stage Fright]]'' (1950),<ref>Callahan, Dan (2020).

The rest of Grenfell's stage career was in a series of solo shows in London and on tour. Between 1957 and 1970 she gave her show ''Joyce Grenfell'' in Australia, Canada, Hong Kong, New Zealand, Singapore, Switzerland and the United States, as well as around Britain and in the West End. Her last live performance was at [[Windsor Castle]] for the Queen's Waterloo Dinner in 1973.<ref>Hampton (2003), p. 98</ref>
