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.
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.
