She's big, she's black and she chain-smokes cigars - but only the best Havanas. Hilda Oates, Cuba's raunchy cabaret artist and ardent patriot, is letting her seat wave, as well as her beloved national flag, over Islington's Pleasance Theatre for at least the next three months. Hilda, 75, stars in Lady Salsa, an award-winning new musical, put together by British director Toby Gough, which has transferred from a sell-out season at the Edinburgh Festival.
