Justin has spoke many times about his guitars, still I can never get enough info on that topic (like what strings does he use and so on), but I've never heard or read his thoughts on his singing. Has he had professional tuition or is it just natural talent and a desire to get good at it? Does he do vocal warm ups before a show, if so what are they? Which singers inspired him to sing? Are there any drinks he likes to have or avoid before singing? how does he keep it in good shape over a long and hopefully not soon to end career? What advice would he have for young/novice singers?
