Actors Roger Bart (Young Frankenstein), Brian d'Arcy James (Next To Normal), Priscilla Lopez (In The Heights) and Sherie Rene Scott (The Little Mermaid) -- collectively veterans of more than 30 Broadway and off-Broadway musicals -- talk about the differences between performing in musicals and straight plays; acting techniques and voice training; how they prepare for a performance; dealing with the "triple threat" of acting, singing and dancing; balancing their lives on and off stage and their opinions on today's new composers.
