I recently watched 'The Voice' and was impressed with what I heard, and it got me interested.  While surfing YouTube, I found out that Keith Urban judges on the Australian version, but that's NOT the surprise.

The first video that came up is an audition by Rachael Leahcar, who is legally blind.  She is led onstage, and she sings so beautifully, to me it sounded like an Angel, and it was enough to make every judge turn around.
