Cajun singer and accordionist Hunter Hayes doesn't know what stage fright is. The 6-year-old recently played for a crowd of at least 160,000. "The more people, the more I'll rock," says the boy from Breaux Bridge, Louisiana. He doesn't understand the French words he sings, but that doesn't stop him. He taught himself to play the accordion at age 3. Now he can play a song if he hears it just once!
