Be forewarned: this is not light reading for the casual Beatles fan. What it is is one of the most stunning examples of scholarship yet exhibited on the Beatles: a finely crafted piece of detective work, one that reconstructs an entire month of Beatles recording sessions and places the available bits and pieces of tape in their proper historical perspective. The focus is tight and meticulous, and so is the research. Far from being a "mere paraphrase of available bootlegs," the authors spent hours upon hours piecing together the "Get Back" puzzle from what was previously a jumbled mess of fragmented bootlegs. The bootlegs are still jumbled and fragmented, but they are no longer a mess. Indeed, the entire Beatles collecting community has quickly adopted this book's method of cataloguing the sundry performances, and you cannot refer seriously to a moment from these sessions without quoting Sulpy and Schweigardt. That, to me, is the most simple and eloquent testimony to the worth of this book. In short, the book is a dense and sometimes tedious micro-examination of one month of the Beatles' lives. But that month was, by its very nature, dense and tedious. The authors cannot change the monotony of that history, they can only explain it. They do it eloquently, with a book that not only serves the collector's community by helping identify stray performances, but one that contains an identifiable dramatic arc as the tensions between the bandmembers flare and fizzle, as the group literally disentegrates before our ears. If you are a die-hard, hardcore Beatles fan, you cannot find a more entertaining way to get to know "the boys" better than to obtain a large number of "Get Back" bootlegs and listen while you're reading this book. It is an experience that will never be forgotten.
