This volume is no puff piece; it depicts Jackie Gleason as an irresponsible, arrogant party boy who was unpleasant to work with and essentially lived in his own world, rarely being nice to other people and usually nasty to most of them.
Born to poor parents with an older brother who died in childhood, his mother would be possessive of him while his father would desert the family, never to reappear. Always infected with a passion for performing in front of an audience, he did not stay in school or work any regular job that did not involve performing before an audience. His mother died of ill health and then Jackie would go on performing wherever he could. But all his life he would dress up in fancy clothes and drink and eat a huge amount, and party with male friends. He married an unsuitable woman and have two daughters with her that he hardly visited.
The author mentions having talked to many people who Gleason met in his life, including many performers and people behind the scenes, and looked up many records of what Gleason had done in his life so we can assume the author sprung for accuracy and not gossip. The impression of Gleason presented by the book is not positive, showing what he could and could not do, but also showing the bad way he treated many people. The book itself has its flaws in skipping between time periods and repeating itself; editing would have helped immensely. But from all indications this book presents an accurate if unflattering depiction of Jackie Gleason.
