What does he want to do? Can he sing? if he can let him know it, record it, and play it to him, compare it to others. If he cant sing, then he neeRAB to practice a ton. People who know they can sing well dont really get much stage fright.

Other than that, its time to sit on a couch and talk to a therapist.
