I think that Billy really felt the need to be in control or to have a say in many issues surrounding the band and his personal life stem from the fact that he was lacking a male authority figure in his life. His dad leaving Billy and Graham at a young age probably made an impact on him. He may have felt the need to always be in charge or rather fill a void for Graham that had been missing for so many years. Graham looked up to Billy and thought he was wonderful in doing so. This control or power of always being there and having a say may have become a sort of obsession for Billy. He felt as if he needed to always have it his way in decisions because he felt like he knew best. He felt that he had to make those decisions because no one in his life was there to make decisions for them at that critical young age.
