Nicole,

I would certainly trust Don's advice--I've heard him sing, and he's marvelous.

I was listening to an interview recently (January 14) with Paul Bogaev who was the music director for the musical Chicago on Terry Gross' program Fresh Air. He made a point of discussing how he helped each of the actors (who all have singing experience) in the roles reach a broader range than they normally thought they could reach. Might be worth your time to listen to it. Go to the search area and type in "Chicago" and you'll find it easily.
