It's fair to mention that I've been a friend of the author's for over 10 years, so I may well be biased. However, light entertainment (or LE) is a subject dear to my heart, and I certainly wouldn't hesitate to complain if it hadn't been given a good treatment. Louis' book plays a blinder, being a thoroughly well-researched 354 pages (there aren't 22 pages of notes for nothing), and follows the story of the LE industry from the birth of variety in the middle of the nineteenth century, to the more recent revival in entertainment television in the shape of The X Factor, Strictly Come Dancing and Saturday Night Takeaway, to mention but a few. In essence, this is the definitive work on the genre, weaving a direct link between those early pioneers of variety to today's stars. Where else would you discover the link between Top of the Pops and Billy Cotton's Band Show? It is essential for anyone with even a passing interest in British television, and proves beyond all doubt that there really isn't anything 'light' about guaranteeing quality entertainment for a mass audience.
