It's the kind of turn that happened to the great country of Germany, when Nazis came over and created tragic things, and they had to be told off. And if we continue this kind of violence and accept it in our country, the rest of the world's going to really take care of us, in a very bad way.

The biggest message I've given our team, and I think it's really important, is first of all, no one can take away what happened last year. It's obviously a fun year, a terrific year. But I think a big mistake would be to try to compare themselves or ourselves to last year's team. I think the key really is, and I told them this: for you as a group, you're a different team.

I always feel the audience is my best teacher.

No-one will ever sound as good as Judy Garland as far as I am concerned.

I plan to do my next two albums with Lady Gaga . She is quite a talent.

There's always something every night that I learn from reacting to what the audience is reacting to. You learn what to leave out, what to put in, if you need a little more comedy or more drama.

I left my heart in San Francisco, high on a hill, it calls to me. To be where little cable cars climb halfway to the stars, the morning fog may chill the air, I don't care. My love waits there in San Francisco, above the blue and windy sea, when I come home to you, San Francisco , your golden sun will shine for me.
