Sad news. I can't stand soaps, but mum was a big fan of Coronation Street so as a kid I got to see Betty on screen a lot. I gather she was a genuinely nice person, in spite of a hard early life. Many of the older generation will remember her as a singer. Her voice has echoes of Gracie Fields, as can be heard in one of her wartime hits here
Ironically, before she joined the Rovers Return, she had quit show business for the sake of her health and was running... you guessed it: a pub. Is it any wonder that she looked so natural behind the bar?
