The first thing I do when I receive a new biography is look at the pictures inside. There seems to be a correlation between the rarity of photos/specificity of photo captions in a biography and the level of detail and depth of knowledge presented in the biography’s text. The photos and their captions can give you a good idea of what to expect in the biography, and yet sometimes can raise a red flag (as in the case of a previous Beatles tome).
When you peruse the photos included in “Tune In: The Beatles: All These Years, Volume 1“, you quickly get a sense of how deep the author dove into Beatles history for this comprehensive work. There are three sections of photos in “Tune In” with about 50 percent of the photos rarely, if not ever, seen before.
