I am not sure if there is a busier 21 year old these days. Hunter Hayes isn't what you would call an overnight success. He has been playing various instruments and singing since he was able to crawl and now he has a number-one country song with "Wanted."Josh and I spoke with Hunter on the show about his no. 1 hit, being on the road with Carrie Underwood and being inducted into the Louisiana Music Hall of Fame at such a young age.
