This perhaps reads more as a diary than a Wiggles memoir, and it takes some very highly personal turns throughout the course of the book. While I may not see the same that Greg does in some of the things that have happened through his life, it's important to remember this is his story- so who am I to judge? There are no real wild things in here- Greg is perhaps the most anxiety laden and high-strung of the Wiggles (probably why I liked him so much as a high-strung child myself), but he does offer his soul in this book.
I think my reasoning behind not being quite so into this book is more about fundamentals of literary style than anything else. The book meanders somewhat, and some bits could have gone in editing, but in the end, it does exemplify a truly honest story. The Wiggles were really still just kids when they were catapulted into fame- so going through their autobiographies has shown this in great detail. To those decrying it on the basis of the Elvis business- Page created 'Rock-a-bye Your Bear', which lives rent free in my mind up to this day. If he feels the presence of Elvis around him, I think he's damn well entitled to it at this point.
