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.
