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.
