 It's 6.06 GMT. This is Weekend here on the BBC World Service. I'm Paul Henley. Coming up later this hour, the soprano star who's made a comeback at this year's BBC Proms concerts after a long struggle with bowel cancer. Singing is almost like being an athlete, you know. I didn't realise this before because I just sang naturally since I was a little girl. Now I realise that I should have carried on, I should have carried on and it wouldn't have been such a mountain to climb to get back to where I am now.
