BBC Four celebrates merry midwinter in unique style, with an exhilarating blend of folk tradition and burlesque fun. Energetic 11-piece Bellowhead and Mercury-nominated alternative folkies The Unthanks get together with the impressive young singers Thea Gilmore and Lisa Knapp, plus other special guests. Steered by genial host Paul Sartin, the assembled artists perform seasonal songs of their own alongside yuletide favourites, ranging from folk ballads and carols to parlour songs and carousing dance numbers, with everyone coming together for a final knees-up. Filmed at the atmospheric Shoreditch Town Hall, the setting evokes an old music hall combined with a festive Victorian family parlour, bedecked with garlands, period lamps and fireplace. Even the audience are dressed up in old-fashioned finery and prove themselves ready to kick up their heels.
