The main story is set in a British Military Intelligence Office in Whitehall during 1956, where a small group of foreign affairs analysts find their quiet existence disrupted by the Suez Crisis. Mick Hopper is completing his national service as an interpreter of Russian documents. Bored with his job, Hopper spends his days creating fantasy daydreams that involve his colleagues breaking into contemporary hit songs. Sylvia Berry is married to the violent Corporal Pete Berry. Sylvia is an object of desire for Mick's fellow clerk Private Francis Francis and a middle-aged theatre organist named Harold Atterbow. In contrast to the street-wise Hopper, Francis is a clumsy Welsh intellectual whose academic career has been interrupted by his army call up. The appearance of the bookish niece of a seconded American officer enables the two conscripts to pair off with suitable partners, after initial mismatching. The main theme of the series is conflict between the old order, as represented by the middle-aged officers in Whitehall plus Francis' prudish Uncle Fred and Aunt Vickie, and the new 'rock n roll' generation represented by Hopper and Sylvia. Though chronologically the series is set in the late summer and autumn of 1956 culminating in the invasion of Suez, many of the songs used, including the title song, were not released until later in the 1950s. Some of the side themes include the influence of American rock and roll on British society, the gulf between the senior analysts, who are regular army officers, and the conscripted other ranks, the work of Russian playwright Chekhov, and an appreciation of opulent theatre organs. The unusual context – a military culture transplanted into a civil service style office environment – reflects Potter's own national service during the 1950s.
Lipstick on Your Collar is an expansion of the earlier play Lay Down Your Arms. Some critics view it as being the final entry in the musical trilogy Potter began with Pennies From Heaven and The Singing Detective. This was the final serial produced during Dennis Potter's lifetime and was nominated in 1994 for two BAFTA-awards, in the categories "Best Makeup" and "Best Music".
