It’s true – the British don’t like their girl singers to be too good, they think it smacks of emancipation, and Cilla at least seemed safe. Obviously, she was quite a nice girl. Also, she was respectable and reliable, very clean and quite unsexy, and she played daughter or maybe kid sister, steady date or fiancée, but she played nobody’s mistress at all. She wasn’t like that. Everyone patronized her like hell, waiting for her to fall, but then she didn’t fall after all, she floated instead and she’s still up there now. She won’t ever come down either – she still can’t sing much, she still comes on like a schoolgirl but she’s liked like that and she can’t go wrong. Genuinely, she’s warm and she makes people glow. In her time, she will grow into a pop Gracie Fields, much loved entertainer, and she’ll become institutionalized.
