It's been the work that has carried me and I never wanted to rest on my laurels or go back and do what I done before.

For me to go back and to play for audiences some of whom have been following me for thirty years and some who have found me in the last five or six years, that's really an interesting thing. I have an audience that goes from kids to seventy year olds.

I've had a great metamorphosis in my life. I struggled for a number of years because I was identified with that image of the Seventies.

I'm never going to retire and say, 'This is it. This is my last show.' I will not go on tour - I promised my wife and son no more than two weeks on the road.

When I was 11, I moved to Los Angeles to live with my father and stepmother and my half brothers. I became really close to my stepmother, and I am still very close to my brothers. My stepmother is the actress Shirley Jones, who was in The Partridge Family alongside me, so we worked together for years.

I've been able to go on and have a successful career on Broadway and certainly the last five years in Las Vegas have been amazing.

I was silver-white by the time I was 35, but having grey hair makes me look washed out. My wife and son have both said that grey hair doesn't suit me because I have a boyish face.
