Joan Sims was always theoretically my sister, though she wasn't. Sheila Sim was married to Dickie Attenborough and because they often saw the Queen I suspected Her Majesty thought I was married to Dickie. She was always extra nice, as if she knew me, which she didn't except as an actress. I suppose it was a bit confusing but Sylvia Syms is my own name and it would have upset my father if I'd changed it.
