*A Book of the Year 2019 — Times Literary Supplement* Polari is a language that was used chiefly by gay men in the first half of the 20th century.  At a time when being gay could result in criminal prosecution — or worse — Polari offered its speakers a degree of public camouflage, a way of expressing humour, and a means of identification and of establishing a community. Its roots are colourful and varied — from Cant to Lingua Franca to prostitutes' slang — and in the mid-1960s it was thrust into the limelight by the characters Julian and Sandy, voiced by Hugh Paddick and Kenneth Williams, on the BBC radio show Round the Horne ('Oh Mr Horne, how bona to vada your dolly old eke!').  Paul Baker recounts the story of Polari with skill, erudition and tenderness. He traces its historical origins and describes its linguistic nuts and bolts, explores the ways and the environments in which it was spoken, explains the reasons for its decline, and tells of its unlikely re-emergence in the 21st century. With a cast of drag queens and sailors, Dilly boys and macho clones, Fabulosa! is an essential document of recent history and a fascinating and fantastically readable account of this funny, filthy and ingenious language. 'Richly evocative and entertaining.' — The Guardian 'An essential book for anyone who wants to Polari bona!' — Attitude 'Paul Baker's exuberant, richly detailed history of Polari, a 'secret' language used chiefly by gay men in the 1940s and 1950s, is a delightful read.' — Tatler 'Intriguing and often amusing...Baker's interviews radiate warmth and good humour.' — Spectator 'A compelling history of the linguistic lengths to which gay men had to go to hide in plain sight.' — Observer
