In the midst of a weeks long worth of appearances in support of his new autobiography “What Does This Button Do?”, Iron Maiden vocalist Bruce Dickinson stopped by one of the top the metal bars in the USA in Saint Vitus on Halloween night. The vocalist did a slide show and talked about all the photos in his book. Then he proceeded to toss out a few tennis balls and the person who received a number, that was the chapter Bruce read from. This night he read about his cancer battle. After he answered fans pre-submitted questions. After that was done (which last about an hour), Bruce signed books for the attendees.
