What is the song on this advert?

I was watching the TV when I saw the Corsodyl advert about how bleeding gums lead to tooth loss. Basically there is a woman who puts on her dressing gown,takes off her make up and false eyelashes and fake tooth. But the song in the background is a cover version of tainted love by a female singer, it's slowed down and is mainly piano but I can't find it anywhere :( does anyone know who it is?
