Hmmm... well I grew up watching all the classic movie musicals, King & I, Sound of Music, West Side Story, etc. I'd watched The Wizard of Oz & Annie a ridiculous amount of times growing up, and they continue to be favorites. Actually, WOZ is my fave movie of all time.
But I didn't see my first Broadway show until I was 15 and that was CATS. Thank God I fell in love with the show and the experience because it brought me back x-amount of times. :)
The first show to really impact me was Jekyll & Hyde, after the whole "I'm gonna be a CAT" phase. haha Then, I was going to be Lucy Harris!
