'The Manual' works both as a set of detailed instructions on how to create a pop single ("it must consist of an intro, a verse, a chorus, a second verse, a second chorus, a breakdown section, back into a double length chorus and an outro. As for lyrics, you will need some, but not many"), and as a capsule portrait of the pop world in the late-80s, a world dominated by manufactured pop acts, Top of the Pops, dance music and samplers - very much like today, in fact.
It's written in a world-weary, cynical style, like a crustier Obi-Wan Kenobi - and Drummond and Cauty know what they're talking about, having both worked in the music industry for a decade before writing this book. 'The Manual' is amoral, non-partisan, and unsensational; they praise Pete Waterman and Michael Jackson, and whilst they guarantee that you'll get to number one (or at least have a decent pop career), they make it clear that you probably won't enjoy the end result.
It's at least as relevant now as it was back in 1989...
