When 14-year-old Jack Vidgen informed the "Australia's Got Talent" judges that he'd be singing "I Have Nothing" by Whitney Houston, they expressed serious doubts. By the final note, however, Jack had completely won them over.

Whitney Houston has firmly established herself as a musical legend, and her songs are considered among the most difficult to perform well. So, upon learning Jack's song choice for his audition, one judge responded, "You're either going to be amazing or dreadful." Luckily for them — and for all those listening — Jack proved himself more than capable of belting out this "big" song.

Listen to the goosebump-inducing performance in the video below, and be sure to watch for one judge's unprecedented reaction.
