Memoir written from inside the entertainment industry can go two ways: score-settling or storytelling. Over the Top and Back, the title bringing Tom Jones into our catalogue, is shelved across arts and entertainment alongside biography, and it runs twelve hours and twenty-six minutes, which is the length of a proper life story rather than a promotional exercise.
The scale of the listener response is the other clue worth noting. Very few memoirs gather a four-figure body of reviews, and the ones that do tend to be the ones people finish and then talk about afterwards.
On the author we stick to the work; the memoir is where that account properly belongs.
