So why would you want to put what you do on YouTube and give it away for free? You might want to ask Argentinia's Josefina Scaglione and how she got from Buenos Aries to be currently cast by Arthur Laurents as Maria in his latest production of West Side Story:
From the Wall Street Journal's article on January 9, 2009:
"She has this incredible, ineffable something," the director says. "She's trained as an opera singer, she's trained as a ballet dancer and she's trained as an actress. It's unbelievable in somebody that young."
This is the video that led to her discovery.
