DuffyDuffy’s hit ‘Mercy’ might have reached number 1 in 15 countries around the world and hit the top 10 in another 17, but she’s revealed that it was only when Bon Jovi covered it during their recent tour that she realised she was famous.

She told Spin magazine recently: “It’s a strange feeling when a person at that level is playing a song I wrote.

“It’s like, ‘Oh my gosh, I’m really here now. [Jon] Bon Jovi knows that I exist.’

“A girl from Wales - that’s all I am, really.”
