Most actors are very grateful for what is as opposed to what will be. You spend 98% of your time looking for a job, so when you get it, it's fantastic.
I sang a lot growing up; I always loved music.
I know how I felt when I saw things like 'Fame' on television when I was growing up and how that was an exceptional magnet for me to want to explore the theater. I can only assume that 'Smash' is doing that for anyone who is halfway interested in theater already.
