Cilla can sing but not like Sandie or Dusty. Her voice can be a little 'thin' for me if you get what I mean.
She lost all appeal when she became an 'entertainer' as far as I'm concerned. I used to like her voice, especially when singing tracks like You're My World, but ever since that TV show where she sings Surprise Surprise (I can't remember what that show was called now!! LOL) it sort of soiled everything good she'd ever done prior to that.
Remember that TV show called Please Sir? Well, for the film version, she recorded a track which was so awful it was great!
"La La La Lu, I love you-o-o, La La La Lee, do you love me-e-e..." Love it! Luckily this can't be spoilt by Surprise Surprise cos it's already crap! Crap in a confusingly good way!
