It is telling that there were drama critics at the Apollo to review Camille O’Sullivan’s show, The Dark Angel. The half-French, half-Irish woman is ostensibly a singer, but so unique is her delivery that each song is a piece of theatre in its own right. My companion confessed to being just a little scared of O’Sullivan, who has a distinctive look - part vamp, part cabariste, but wholly diva. She described the singer, with her raven hair and a gash of bright-red lipstick, as “a cross between Tracey Emin and Judy Garland”, but soon warmed to her. But then O’Sullivan is a pussy cat, as evidenced by her slinky movement about the stage and exhortations of the audience to miaow (“my favourite sound”) at her.
