Notwithstanding a deliberate false start, their opening track, Confidence, establishes the feminist swagger coursing through their set, and the sort of direct, expletive-punctuated responses to misogyny and brazen stupidity that is their stock-in-trade. Indeed, a running folk ballad, in the vein of Scarborough Fair, finds the protagonist adopting a #TimesUp stance of hip hop-endowed empowerment to put would-be suitors and haters firmly in their place.

Elsewhere, a trip they took to Disney World found the Florida hospitality a little too right-on, and they capably mock the certitude of anti-vaxxers, suggesting ulterior motives in a tune that showcases their versatility. Pulling an Irish Goodbye extends the Celtic theme of the slur with the traditional sound of bodhrán and tin whistle, a wake disappointing in its potential for hooking up. With Nicola generally sat deadpan beyond her keyboard, Rosie, on drums – a bone of contention between them – is more expressive. Starting to freeze each other out in affected dispute, they nevertheless reconcile their differing styles in a sober-enthusiastic, melodically hybrid finale. Entertaining without reinventing the musical comedy genre.
