The themes I sing about tend to be centered on love, but in the most total, general way 360 degrees of love.

I don't know if One Direction will stand the test of time. I have a niece who goes crazy for them. But the only way to judge art is to wait and see if it becomes evergreen. This takes a bit of time. Adele is a very good musician and I'd like to sing with her. But, again, time will tell if her music will become evergreen.

Classical music and pop are two different universes, each with its own difficulties, peculiarities, depth and artistic dignity. In Italy, I think there is a fairly clear line of demarcation, but the history of music is full of fusion. Popular and classical music have always found points of contact, of crossing, exchange, both drawing mutual profit.

My life experience has taught me nothing happens by chance. Even the idea of the ball in a roulette game: it's not chance it ends up in a certain place. It's forces that are at play.

I have had the good fortune of being able to sing with many of the finest voices in the world, and for someone who loves voices as I do, this is an enormous privilege.

I have always felt an excellent rapport ever since my very first concert in Britain at Hampton Court. I have always felt understood. The British understand opera very well.

When a little more than a teenager, I was a piano-bar pianist in the land where I was born and raised, Tuscany.
