I got fitter when I did 'Joseph and the Amazing Technicolor Dreamcoat.' I wore a loincloth - that's a lot of motivation!

Of course this is Vegas and it is the melting pot for all over the world, but people from all over the world know Donny and Marie. It is amazing. I have been in the business a long time to realize careers can be fleeting. Five years is a long career nowadays for some people, and here we are still going strong after 40 years.

My father instilled in me the attitude of prevailing. If there's a challenge, go for it. If there's a wall to break down, break it down.

I could play it safe by recording songs that are familiar, but am I expanding myself as an artist by doing covers? It's a catch-22. It's called show business: The word 'business' is in it, and you've got to be a businessman. But then again, you have to be true to yourself as an artist.

It's a lot of work to keep reinventing yourself and coming up with new stuff, but that's what it takes to be in show business.

A belief in God is vitally important, not just in show business, but stability in life. You know, to recognize deity is the most important thing that you can do. I mean, it comes to the Ten Commandments. They weren't ten suggestions. They were Ten Commandments.

I was never considered cool throughout my teens: a very important time to be accepted by someone, especially your peers. Yes, I had all the screaming women, but the guys hated my guts.

Maybe I am a little bit guilty of trying to convince myself that I am cool to this point - even today. But I am so much more healthy than I used to be in my twenties, because I was not accepted at all.

I believe in the institution of marriage. Of course being a Mormon, we believe in eternity rather than just till death do us part. If you really try hard, if you make it work, it's blissful. But I also know a marriage that isn't working can be painful.
