Iron Maiden has sold over 90 million albums, received four GRAMMY nominations, and won the prestigious award in 2011 for Best Metal Performance. The band's lead singer, Bruce Dickinson, joined us to reflect on his adventurous career. Dickinson is a man of many talents, and details it all in his first autobiography titled "What Does This Button Do?" Dickinson opened up about how a battle with throat cancer inspired him to talk about his journey in his new book. Not only was Dickinson an all-star on the stage, but he also made it as a successful pilot. After mastering the trade, Dickinson showed his entrepreneurial side by founding his own aviation repair company.
